even think about it?
Today we will find out the
answers to these questions.
Living things have systems
that control, regulate, and
coordinate
body processes.
D. Discussing new
concepts and
practicing new
skills #1
The human body is a complex, highly organized structure
made up of unique cells that work together to accomplish
the specific functions necessary for sustaining life.
The Respiratory System
When the respiratory system is mentioned, people generally
think of breathing, but breathing is only one of the activities
of the respiratory system. The body cells need a
continuous supply of oxygen for the metabolic processes
that are necessary to maintain life.
The respiratory system works with the circulatory system to
provide this oxygen and to remove the waste products of
metabolism. It also helps to regulate pH of the blood.
Main Parts of the Respiratory System
∙ Nasal Cavity
The nostrils are the opening into the nasal passages that are
The Nervous System and its Function
The Nervous System is the control unit of the body . Its function
is to integrate and coordinate bodily activities. It coordinates
the activities and communicates with the sense organs and
the other body systems through the wire like nerve cells or
neurons that transmits messages passing
through spinal cord to the brain and back to the nerve cells or
neurons for the interpretation of the senses .
The brain is an amazing organ that performs different functions
such as processing memory, judgement , and reasoning. It
controls body movement, emotions , feelings and vital sign of
life such as breathing. The brain has three main parts:
cerebrum , cerebellum and the brainstem or
the medulla oblongata. Another organ in the nervous system
is the spinal cord. It a cord like material inside the backbone. It
Structure and Functions of the Central
Nervous System
The Central Nervous System (CNS) controls
and coordinates the activities of the
whole nervous system. It is composed of the
brain and spinal cord. The skull and vertebrae
enclose the CNS. Fluid and tissue fill and
insulate the brain and spinal cord. The central
nervous system is like a telephone system with
a central computer operator present to
process incoming phone calls. It contains
structures that receive and process numerous
stimuli every minute.

4. lined with hairs. Nostrils
have cilia. The cilia filter the dust and other particles present
in the air. They also protect the nasal passages and other
regions of the respiratory tract. The blood vessels inside the
lining of the nose arms and humidifies the air.
∙ Pharynx and Larynx
The pharynx is also called the throat. It is the common
passageway for both food, water, and air. Below the
epiglottis is the larynx or voice box. The larynx contains two
vocal cords that vibrate when air passes by them. With our
tongue and lips, we convert these vibrations into speech.
The larynx is the main site for sound production. Two
ligament called vocal chords can be stretched in varying
extent across the opening to the larynx.
∙ Trachea, Bronchi, Bronchioles, and Alveoli
The trachea is known as windpipe. It is made up of muscles
and elastic fibers with rings of cartilage lined with cilia. The
trachea filters the air we inhale and branches into the
bronchi. The bronchi are two tubes that carry the air into the
lungs. Bronchial tubes also branch into smaller tubes called
bronchioles. Alveoli are grape-like structures at the end of
bronchioles. The alveoli have thin walls that are surrounded
by blood vessels.
● Lungs
The lungs are located in the chest cavity surrounded by
the rib cage. The lungs are the main organ of the
respiratory system. This is where exchange of gases occurs.
This is the site where oxygen is taken in and carbon dioxide
is expelled out.
∙ Diaphragm
The diaphragm is a dome-shaped muscle that controls
breathing, which is located at the bottom of the lungs.
During respiration, the diaphragm flattens out and pulls
forward, making more space for the lungs. When we
inhale or breathe in, the diaphragm contracts and pulls
downward. When we exhale or breathe out, the
diaphragm expands.
bridges impulse between the brain and the body. This means
all the signals that go to and from the brain pass through the
spinal cord and deliver it to the right muscles and senses .
Neuron is also another organ in the nervous system. It is a wire
like organ that is found all over the body. Its main function is to
deliver messages within the nervous system and between
other body system. It is divided into three parts: axon, cell
body and dendrites .Neurons can be classified based on the
direction in which they send information .These can be sensory
neurons , motor neuron and inter neuron .
The hypothalamus regulates homeostasis.
Homeostasis enables an organism to
maintain internal balance in the body. The
thalamus serves as a central relay point for
incoming nervous messages.
The Spinal Cord
The spinal cord extends from the brain stem
down to the buttock region. A bony
vertebra that comprises the vertebral column
protects it.it allows signals to be sent from the
brain to the other parts of the body. It also
receives messages from the different parts of
the body to the brain.
∙ Somatic Nervous System (SNS) – includes all

5. nerves controlling the muscular system
and external sensory receptors.
∙ Autonomic Nervous System – is a part of PNS
consisting of motor neurons that control
internal organs.
∙ Sympathetic Nervous System – is involved in
the fight or flight response.
∙ Parasympathetic Nervous System – is
involved in relaxation.
E. Discussing new
concepts and
practicing new
skills #2
Directions: Fill in the missing
organs in the box. Write the
answers on the box
provided.
Determine if each sentence is
correct or incorrect. Write
C on the line if it is correct. If it is
Incorrect, encircle the word(s)
that
make(s) it incorrect and write
the correct word(s) on the line.
_________1. The cerebrum is the
largest part of the brain
_________2. The brain is the
control center of the nervous
system.
_________3. The brain is made up
of the cerebrum, cerebellum
and spinal
column.
_________4. The nervous system
consists of the heart, brain and
spinal
column.
_________5. The nerves interpret
the meaning of what is
perceived by the
sense organs.
Role of the Nervous System
The body system that
controls other parts is the
nervous system. The
nervous system
receives signals or stimuli
from inside and outside
our body. A stimulus is an
agent or factor
that provokes interest,
enthusiasm, or excitement.
A response is the reaction
of an organism or any part
of its body to a stimulus.
The neuron or nerve cells is
the functional unit of the
nervous system. Neurons
have three parts:
∙ The dendrites are the
short and highly branched
part that receive
information a receptor
organ or another neuron
and then transmit the
messages to the cell of the
body.
∙ The cell body contains
the nucleus, mitochondria,
and other cellular
organelles.
∙ The axon is the long and
less-branched part that
conducts the information
away from
the cell body.
Three Types of Neurons:
∙ Sensory Neuron – carries
messages from the
receptor organs (skin,
eyes, nose, ears, and

6. tongue) to the nerve
centers.
∙ Motor Neuron – receives
information from the nerve
centers and transmits it to
the
effector organs (muscles
or glands).
∙ Interneurons – are found
only in the central nervous
system (brain or spinal
cord).
