2. Processes in Plants and Animals (Gas Exchange and Transport/Circulation) Tuesday, February 2, 20XX Sample Footer Text 2

3. Introduction One of the most essential events in everyday life of a living organism is the exchange of gases. This process is important as it keeps organism alive. Tuesday, February 2, 20XX Sample Footer Text 3

4. OBJECTIVES Monday, May 16, 2022 DRRR 4 At the end of the lesson, the learners will be able to: Describe the organs in the human respiratory and circulatory system and their roles. Discuss the coordination of gas exchange and circulation. Trace the path of blood in the systemic and the pulmonary circulation

7. THE HUMAN RESPIRATORY SYSTEM 7 To help you breathe, the respiratory system has several different parts that function together. Your airways deliver your lungs with air. Your airways are a complex structure, like your: Mouth and nose: Openings that pull air from outside your body into your respiratory system. Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe). Larynx- narrow opening that leads into trachea Trachea: Passage connecting your throat and lungs

8. THE HUMAN RESPIRATORY SYSTEM 8 Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. • Lungs: Two organs that remove oxygen from the air and pass it into your blood. Some of the bones and muscles in the respiratory system include your: ** Diaphragm: Muscle that helps your lungs pull in air and push it out ** Ribs: Bones that surround and protect your lungs and heart

9. When you breathe out, your blood carries carbon dioxide and other waste out of the body. Other components that work with the lungs and blood vessels include: ** Alveoli: Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. **Bronchioles: Small branches of the bronchial tubes that lead to the alveoli. **Capillaries: Blood vessels in the alveoli walls that move oxygen and carbon dioxide. **Pleura: Thin sacs that surround each lung lobe and separate your lungs from the chest wall. 9

10. Passage of Air in Respiratory System The air we breathe goes through the nose, nasal passages, and then through the trachea or windpipe, which separates into two branches, called bronchial tubes or bronchi, one entering each lung. The bronchi subdivide many times inside the lungs, analogous to the branching pattern of grapes, finally becoming hairlike tubes called bronchioles. In the last part of the terminal bronchioles are tiny bubble-like bunch of structures called alveoli or air sacs. Tuesday, February 2, 20XX Sample Footer Text 10

11. THE HUMAN CIRCULATORY SYSTEM 11

12. THE HUMAN CIRCULATORY SYSTEM 12 The following are the three major parts of the circulatory system, with their roles: 1.Heart – pumps the blood throughout the body 2.Blood vessel – carries the blood throughout the body Arteries - carry oxygenated blood away from the heart to the cells, tissues and organs of the body Veins - carry deoxygenated blood to the heart Capillaries - the smallest blood vessels in the body, connecting the smallest arteries to the smallest veins - the actual site where gases and nutrients are exchanged 3.Blood – carries the materials throughout the body

13. THE HEART The Aorta:  this is the largest artery in the human body. The main function of the aorta is to take oxygenated blood all the way from the left ventricle to the rest of the body. The Pulmonary Artery:  this artery is responsible for carrying deoxygenated blood all the way from the right ventricle to the lungs. The Right Atrium:  this part of the human body is tasked with receiving deoxygenated blood from the rest of the body. Tuesday, February 2, 20XX Sample Footer Text 13

14. THE HEART The Pulmonary Vein:  Veins are the tubular branching vessels that carry blood all the way from the capillaries and take it to the heard. The function of the pulmonary vein is to take oxygenated blood all the way from the lungs to the left atrium. The Left Ventricle:  A ventricle is any of the cavities of a bodily part or organ. The essential function that the left ventricle carries out is pumping oxygenated blood into the aorta. The Right Ventricle:  The right ventricle is tasked with pumping deoxygenated blood into the pulmonary artery. Tuesday, February 2, 20XX Sample Footer Text 14

17. Pulmonary Circulation The circulation of the blood through the heart starts when blood comes back to the heart through two big veins called the  vena cava . > The blood then flows into the  right atrium . > Then it passes through the  tricuspid (3-cupped) valve  into the  right ventricle . > From there, it is pumped through the  pulmonary arteries  to the lungs. In the lungs, it picks up oxygen and drops off carbon dioxide. 17

18. Systemic Circulation . 18 > Then it comes back to the heart through the 4  pulmonary veins  and flows into the  left atrium . > Then it goes through the  bicuspid (2-cupped) valve  (also called the  mitral valve ) into the  left ventricle . > The left ventricle, the most muscular and powerful chamber in the heart, pumps the blood through the  aorta , the largest artery in the body. From here, the blood flows to the whole body, bringing oxygen to the tissues that need it. This is called the  Systemic Circulation .  

19. ELABORATE Tuesday, February 2, 20XX Sample Footer Text 19 Activity: Think-Pair-Share Cigarette Smoking Is Dangerous to Your Health   Look for pictures of a smoker’s body on the internet. Take note of the illnesses that might develop due to cigarette smoking. (http://www.clarkisit.com/smokingkills) With your pair, brainstorm ideas about the effects of cigarette smoking on a person’s respiratory and circulatory systems using the meta plan strategy. After discussing the ideas within the group, write and organize all the responses on a bond paper to categorize which answer falls under the respiratory and circulatory systems. Refer to the example given below.
