Respiratory System
respiratory system, the system in living organisms that takes up oxygen and discharges carbon
dioxide in order to satisfy energy requirements. In the living organism, energy is liberated, along with
carbon dioxide, through the oxidation of molecules containing carbon. The termrespiration denotes
the exchange of the respiratory gases (oxygen and carbon dioxide) between the organism and the
medium in which it lives and between the cells of the body and the tissue fluid that bathes them.
With the exception of energy used by animal life in the deep ocean, all energy used by animals is
ultimately derived from the energy of sunlight. The carbon dioxide in the atmosphere in conjunction
with the energy of sunlight is used by plants to...show more content...
The amount of oxygen available in natural waters is also limited by the amount of dissolved salts.
This factor is a determinant of oxygen availability in transitional zones between sea and fresh
water. Pure water, when equilibrated with oxygen at 0В° C, for example, contains about 50
millilitres of oxygen per litre; under the same conditions, a solution containing 2.9 percent of
sodium chloride contains only 40 millilitres of oxygen per litre. Bodies of water may have
oxygen–poor zones. Such zones are especially evident in swamps and at the lower levels of deep
lakes. Many animals are excluded from such zones; others have become remarkably adapted to
living in them.
The Earth's atmosphere extends to a height of many miles. It is composed of a mixture of gases
held in an envelope around the globe by gravitational attraction. The atmosphere exerts a pressure
proportional to the weight of a column of air above the surface of the Earth extending to the limit
of the atmosphere: atmospheric pressure at sea level is on average sufficient to support a column of
mercury 760 millimetres in height (abbreviated as 760 mm Hg–the latter being the chemical symbol
for mercury). Dry air is composed chiefly of nitrogenand inert gases (79.02 percent), oxygen (20.94
percent), and carbon dioxide (0.03 percent), each contributing proportionately to the total pressure.

The Respiratory System Essay
The respiratory system is the process responsible for the transportation and exchange of gases into
and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the
lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the
lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and
through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters
the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs,
through a process known as diffusion, the oxygen is transferred to the blood stream through the
alveoli (air ducts) where it is then transported inside...show more content...
Within the alveoli, the oxygen is transferred to the blood whilst simultaneously collecting waste
carbon dioxide for excretion as we breath out. This transference is known as diffusion and is linked
to the cardiovascular system.
Diffusion is an automated process by where the levels of oxygen, water and carbon dioxide pass
over a 'semi–permeable membrane' between the walls of the cells and blood vessels to create a level
environment. This membrane only allows these three elements to pass whilst retaining other
elements such as blood cells, hence semi–permeable. The high concentration on one side of the cells
transfers through this membrane until the level is equal on both sides.
The human body comprises of two respiratory sponges called lungs. The left lung is slightly smaller
than the right as it makes room for placement of the heart. Due to this slightly smaller size, it only
contains two lobes whereas the right lung has 3 lobes. Both lungs are host to the network of air sacs
or alveoli which transport the air from the outside environment to the external and internal respiration
processes.
As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles
to contract and expand the chest. The diaphragm is contracted and moves down as the area inside
the chest increases as air enters the lungs. The lungs are forced open by this expansion and the
pressure inside the lungs becomes enough that it pulls

Respiratory System Analysis
The respiratory system changes in many ways as one ages. These gradual changes begin at age
twenty to thirty (Miller, 2015, p. 443) and function starts to weaken at age forty (El–Kader, and
El–Den Ashmawy, 2013, p. 15). Changes occur in the upper respiratory structures, chest wall and
musculoskeletal structures, and lung structures and function. The upper respiratory structures in the
nose become less supportive, due to less connective tissue, and smaller, because of decreased blood
flow (Miller, 2015, p. 443). Also, degenerative changes in the submucosal glands of the
nasopharynx produce thicker mucus (Miller, 2015, p. 443). Cough and gag reflex are decreased
(Miller, 2015, p. 443). Because of chest wall and musculoskeletal changes, elderly spend more
energy on breathing. This occurs as a consequence of chest wall stiffness, weakened muscles, and
changes in the shape of the chest (Miller, 2015, p. 444). The lungs become less elastic and smaller,
the alveoli enlarge and thin out, the pulmonary artery becomes stiffer, wider, and thicker, the
pulmonary capillaries decrease and have less blood flow, and the mucosal bed thickens (Miller,
2015, p. 445). Elastic recoil diminishes and can cause air trapping and less gas exchange (Miller,
2015, p. 445). Due to changes, elderly do not always respond in a compensatory manner and can
have mental changes instead (Miller, 2015, p. 445). Nursing interventions for the respiratory system

In our book Elsevier says, "Because this amount comes and goes regularly like the tides of the
sea, it is referred to as the tidal volume (TV)." The book also states, "The largest amount of air
taken in one expiration is known as the vital capacity (VC)." (Elsevier 2008). People that have
diseases such as lung disease, emphysema, and heart problems have their tidal volume and vital
capacity checked on a normal basis since conditions such as those can cause an abnormal amount
of air going in and out of the lungs. When we use a lot of energy that requires us to use more
oxygen since oxygen is what gives us the energy we need. The harder we work or run or do
activities the more oxygen we need to intake to give to the millions of cells in the body. This is
the reason when we run we breathe harder and deeper because our body is trying to keep up with
us. When we breathe harder and faster our heart is also beating faster which is causing blood to
pump more through the body each minute. Therefore the red blood cells make more trips and
deliver more oxygen to the tissue cells also getting rid of more carbon dioxide than if we were
doing nothing. Located in the medulla and pons of our brain is what is called the respiratory
control center. In our book on page 382 it says, "These centers are in turn regulated by a number of

The Cardiovascular and Respiratory Systems in Correlation to the Heart

Introduction
The cardiovascular system serves the body as a way of transporting blood all throughout the body.
The cardiovascular system is composed of two circuits, the pulmonary and systemic circuits. In the
pulmonary circuit, deoxygenated blood is carried away from the heart, into the lungs, and returns
back again to the heart as oxygenated blood. The systemic circuit works to carry all of the
oxygenated blood that the pulmonary circuit has produced to all over the body, and in return gives
more deoxygenated blood to the heart. (Circulatory system) The respiratory system has three
different parts; External respiration, internal respiration, and gas transport. These systems work to
inhale oxygen and to exhale carbon dioxide. Red blood cells gather the oxygen that has been
stored in the lungs, and deliver it to wherever oxygen is needed throughout the body. Once the
oxygen is transported, the red blood cells gather carbon dioxide and return it to the lungs where it
is then exhaled. One reason that the red blood cells need to carry out carbon dioxide is because it
can form acid in the blood. (BSC 228 Biopac, Fall 2016) When the heart is pumping against
gravity, heart rate and blood pressure should increase. Heart rate should also increase following
exercise before returning to a normal level. During

The Respiratory System
The respiratory system consists of different structures that all function together to deliver oxygen to
the lungs and expel carbon dioxide from the body. The respiratory system consists of structures such
as the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and the lungs. The
primary function of the respiratory system is gas exchange but other functions also include sound
production, assistance in abdominal compression, and coughing and sneezing. The lungs are the
main organ of the respiratory system. The function of the lungs receiving the oxygen from the air

The walls of the bronchioles thicken, become enlarged and they tighten up. The structure in the
bronchioles causing the airway to tighten up is the elastic fiber and smooth muscle. They constrict
making it very difficult for a patient to be able to take in air. This makes the process of oxygenation
hard because very little oxygen is being able to reach the alveoli. The reasoning for bronchiole
constriction during asthma can be a number of things, but the bronchioles usually rapidly constrict
when they come in contact with the substance. For example during allergic asthma bronchioles can
constrict when airways come in contact with allergens, such as if someone is allergic to dogs and
they come in close contact with a dog. The hyperresponsiveness of the bronchioles is a sensitivity to
stimuli. The symptoms patients acquire when suffering from asthma can be, coughing, chest
tightness and, shortness of breath. When a person coughs when having asthma the coughing comes
from the person feeling as though something is obstructing their airways. They cough to try to help
clear their airways. The wheezing a person experiences comes from when the bronchioles are
constricted and it makes it difficult to breathe the closed up airways causes a whistling noise occur
when you breathe out. Chest tightness during asthma happens because in the lungs there are no

Respiratory System Essay
Respiratory System
The respiratory system consists of a series of tubes that air passes on its journey from the nostrils.
The nostrils open into the nasal cavities, which are lined with moist eiliateol epithelium. Whether
one breathes through the nose or the mouth, a breath of air enters the body and flows through the
nasal cavity to the pharynx (throat). The back of the nasal cavities is continuous with the throat
region, or pharying. Air flows through the larynx (voice box) and into the trachea, which divides
into two bronchi, one going to each lung. The trachea and bronchi are supported by C–shaped rings
of cartilage that prevent the tubes from collapsing as air is drawn into the body. The bronchi divide

The lungs are large paired spongy organs in the thoracic cavity. The right lung is divided into three
lobes, and the left into two lobes. Each lung is covered with the pleural membrane that forms a sac
enclosing the lung and the lining of the chest cavity. The lungs consist largely of air tubes and
elastic tissue. They are spongy, elastic organs with a very large surface area for gas exchange.
Breathing is a process of moving air from the environment into the lungs and expelling air from the
lungs. Inhaling air is referred to as inspiration, exhaling is referred as expiration. An adult breathes
about 12 times each minute. During inspiration, the chest cavity is expanded by the contraction of
the diaphragm, the muscle of the thoracic cavity. When the diaphragm contracts, it moves
downward, increasing the volume of the thoracic cavity. Expiration occurs when the diaphragm and
rib muscles relax. The respiratory system delivers oxygen to the air sacs but the vital link between
air sac and body cell is the circulatory system. Each air sac serves as a tiny depot from which
oxygen is loaded into blood brought to the alveolar air by capillaries. Oxygen molecules diffuse
from the air sacs into the blood because the air sacs contain a greater concentration of oxygen than
does blood entering the pulmonary capillaries. Carbon dioxide moves from the blood where is is
more concentrated to the air sacs, where it is less concentrated. Each gas diffuses through the

RESPIRATORY SYSTEM The respiratory system consists of all the organs involved in
breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory
system does two very important things: it brings oxygen into our bodies, which we need for our

The Diaphragm and Intercostal Muscles When you breathe in (inspiration), your muscles need to
work to fill your lungs with air. The diaphragm, a large, sheet–like muscle which stretches across
your chest under the ribcage, does much of this work. At rest, it is shaped like a dome curving up
into your chest. When you breathe in, the diaphragm contracts and flattens out, expanding the space
in your chest and drawing air into your lungs. Other muscles, including the muscles between your
ribs (the intercostal muscles) also help by moving your ribcage in and out. Breathing out
(expiration) does not normally require your muscles to work. This is because your lungs are very
elastic, and when your muscles relax at the end of inspiration your lungs simply recoil back into their
resting position, pushing the air out as they go.
PHYSIOLOGY The diseases and disorders of the respiratory system can affect any part of the
respiratory tract and range from trivial to life–threatening. The nasal passages and pharynx, for
example, are targets for the viruses that cause colds. These viruses infiltrate and destroy the cells of
the nasal passage membranes. The immune system fights back by increasing blood flow to the area,

Cardiovascular And Respiratory System Essay
When we breathe in air through the nose, our lung fill with oxygen. This happens when the oxygen
passes through the pharynx then the larynx and then to the wind pipe (trachea). This air travels
through the bronchi and then travels to the alveoli through the bronchioles which are small sacs.
Gas exchange takes places at the alveoli and the alveoli are surrounded by capillaries which are blood
vessels. The Respiratory System is needed in order for oxygen to be released into the bloodstream
and for the blood to circulate around the body. Energy comes from a lot of different foods such as
fats, sugars, carbohydrates and proteins. "Our bodies digest the food we eat by mixing it with fluids

Anatomy And Physiology Of The Respiratory System
Section 1 : Anatomy and Physiology
The respiratory system, also known as the ventilatory system, is a series of organs found in the
human body. The system's primary function is performing respiration – inhaling oxygen from the
environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts
as fuel – without it, the body would be unable to function. Carbon dioxide, the by–product of this
process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine, 2016).
The main organs of the respiratory system are the lungs – they are the location where the gas
exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you
breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle
that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself
downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the
possible area the lungs can expand to. This pressure causes air to be sucked through the body to the
lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to
normal, allowing the process to happen again.
Air can be breathed in through both the nose and the naval cavity, or the mouth, also known as the
oral cavity. The air, regardless of the path taken, will always lead to the pharynx, a space located at
the back of throat. It will progress through the larynx,

The Respiratory System Essay
The respiratory system is a complex organ structure of the human body anatomy, and the primary
purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the

system completes this important function of breathing throughout inspiration. In the breathing
process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks,
but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange
of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies &

The Five Key Functions Of The Respiratory System
I have chosen the respiratory system as my body system. It removes the carbon dioxide from the
body whilst providing the body with the oxygen that it needs. There are 5 main key processes that
the respiratory system control.
They are:
Breathing
–moving air through the nasal cavity to the lungs and back out. It is also called ventilation.
External respiration
–gases within the air and in the blood exchange between each other.
Gas transport by blood
–the cells of the body receive oxygen and transport it around the body and expel the CO2.
Internal respiration
–gases within the blood and the cells in the body exchange.
Cellular respiration
–the cells use up the oxygen to perform their duties and the production of CO2.
(http://hyperphysics.phy–astr.gsu.edu/hbase/Biology/respir.html)
The organs that make up the respiratory system are; nose and nasal cavity, mouth, pharynx, larynx,
trachea, bronchi, bronchioles, alveoli, diaphragm and lungs.
Nose and nasal cavityMain and first opening of the respiratory system. It is made up of three
sections filled with hairs and mucus membranes
MouthAlso known as the oral cavity. Another opening of the respiratory system and can also take air

instead inflicting labored breathing and a hope for a cure.
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over
the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the

Sufferers are required to use energy reserves leaving them quite tired. When emphysema attacks, the
respiratory system goes out of homeostasis due the systems inability to efficiently exchange oxygen
and carbon dioxide, as well as exhausting the energy reserves of the sufferer. A healthy respiratory
system refreshes and energizes a body, efficiently pumping in oxygen and expelling carbon dioxide
without thought or excessive effort.
I have yet to see a benefit from smoking. While it is possible to get emphysema from breathing in
environmental or occupational pollutants, smoking seems to be the number one cause. According to
mayoclinic.com, there are over 4,000 chemicals found in both first and secondhand tobacco smoke
(Emphysema, 2009). Smoke enters into the lungs breaking down the elastic fibers, wreaking havoc
on the entire respiratory system, including the alveoli. Sadly, there is no easy cure. The best first
step is to stop smoking or exposure to the causing pollutants. Afterwards, treatment is to manage
symptoms, and hopefully slow down progression. Those I know with emphysema are treated with
supplemental oxygen tanks to increase oxygen flow, steroids to relieve emphysema related
bronchitis, and bronchodilators to open the air passageways. In a best, or worst, case scenario for

Human Respiratory System Essay
Introduction
The human respiratory system is a series of organs responsible for taking in oxygen and expelling
carbon dioxide. The structural features of the respiratory system include nasal cavity, trachea,
bronchi and lungs. Body cells need a constant supply of oxygen to generate energy to drive
cellular activities, this however creates carbon dioxide as a waste product. Blood delivers oxygen
to cells and removes carbon dioxide. When deoxygenated blood passes through the lungs the
carbon dioxide is removed and replaced with oxygen. Breathing in (inhalation) brings oxygen in and
breathing out (exhalation) releases carbon dioxide out of the lungs. Respiration mainly takes place
in lungs. The lungs comprise millions of tiny sacs called alveoli, which allow for the exchange of
these gases.
Structure of the Respiratory System
The Respiratory system can be broken into the upper and lower respiratory tract. The upper
respiratory tract includes the nasal cavity, pharynx and sinuses whereas the lower respiratory tract
contains the larynx, Trachea, bronchial tree, and lungs.
Air enters the body through nose or mouth, it then travels down the back of your throat and into the
trachea. The trachea then divides into two narrow tubes called bronchi. As the bronchi tubes pass
through the lungs, they each divide into smaller air passages called bronchioles. The bronchioles
branch out, getting smaller and leading to thousands of air sacs called alveoli. The alveoli are

The respiratory system has many supporting systems like the skeletal and the muscular. The first
supporting part are the ribs. This protects the lungs as well as the heart from damage. Without the
ribs, if we got hit in the chest, our lungs would collapse instantly. The other supporting is the large
sheet of muscle below the lungs called the diaphragm. It becomes thinner every time we breathe
which creates more more space for the lungs to inflate.
Your breathing is regulated by the respiratory system control center at the base of our brain. This part
sends messages down the spine to make sure our breathing muscles are contracting a relaxing
regularly which makes breathing automatically unnoticeable until we actually think about it.
However, we can control our breathing rate to some extent for example, by running which makes the
muscles need more oxygen therefore, breathing more deeply.
VO2 max is the maximum consumption of oxygen. VO2 is measured in milliliters. People who
have a lower VO2 value are usually people who are out of shape such as obese people. The average
male VO2 capacity is 3.5 liters per minute and for females, 2.7 liters a minute. The male VO2 max
