  1. 1. THE HUMAN BREATHING SYSTEM
  2. 2. OBJECTIVES: 1. Describe the general function of the Human Respiratory System. 2. Identify the different parts of the human respiratory system. 3. Describe the function of each part of the breathing system.
  3. 3. Respiratory and Circulatory Systems Working with the other Organ Systems
  4. 4. ACTIVITY THE HUMAN BREATHING SYSTEM Respiratory system is made up of the organs in the body that help us to breathe. Just remember that the word respiration is linked to breathing. The parts of the respiratory system that are in charge of supplying oxygen are the nose, nasal passageways, windpipe, lungs, and diaphragm. In the nose and nasal passages, the entering air is made warm, damp, and clean of unknown particles. Next, the air moves down through the trachea, bronchi, bronchioles and alveoli. Trachea is the empty tube that serves as passageway of air into the lungs. Bronchi are the two branching tubes that connect the trachea to the lungs. Bronchioles are the hair like tubes that connect to the alveoli. Alveoli are the air sacs that allow gas exchange in the lungs. 1. Read the background information about human breathing system.

Write the function of each part based on the background information in the box. nasal passage nose trachea alveoli bronchi bronchioles serve as channel for airflow through the nose in which the air is warmed, cleaned and moistened the organ through which the air enters and is filtered. also called airsacs; allow the gas exchange in lungs. also called windpipe; a hollow tube that serves as passageway of air into the lungs also called bronchial tubes; two branching tubes that connect the trachea to the lungs. the finer subdivisions of the bronchi; hairlike tubes that connect to alveoli.
  8. 8. Activity 1B: Procedure: 1. Hold up the bunch of malunggay leaves/grapes to represent the parts of the respiratory system. 2. Within your group, locate the parts of the breathing system. 3. Present in front the analogous parts of the Human Respiratory System.
  9. 9. GUIDE QUESTIONS • 1. What does each part of malunggay leaves represent? • 2. Describe the pathway of oxygen in the breathing system.
  10. 10. GUIDE QUESTIONS: 1. What does each part of malunggay leaves represent? 2. Describe the pathway of oxygen in the breathing system.
  11. 11. The pathway of oxygen The air moves from the nose (nasal cavity/ and mouth (oral cavity) to the trachea, bronchi,bronchioles and then into the alveoli (air sacs). The air we breathe carries gas oxygen. When we breathe, the oxygen goes to the lungs.
  12. 12. QUESTIONS: 1. What are the different parts of the human respiratory system? 2. Describe the function of each part of the breathing system.
  13. 13. Respiratory System – made up of the organs in the body that help us to breathe. PARTS AND FUNCTION • Nose - the organ through which the air enters and is filtered. • Nasal Passages - serve as channel for airflow through the nose in which the air is warmed, cleaned and moistened • Trachea - also called windpipe; a hollow tube that serves as passageway of air into the lungs. • Bronchi - Two branching tubes that connect the trachea to the lungs. • Bronchioles - Hair-like tubes that connect to the alveoli. • Alveoli - The air sacs that allow gas exchange in the lungs •
  14. 14. APPLICATION What will happen if one part of the system fails to carry out its function properly?
  15. 15. APPLICATION What will happen if one part of the system fails to carry out its function properly? All parts in the breathing system needs to work as one, they should have teamwork to continue their work and their function. If one part of the system fails to carry out its functions properly, the air we breathe cannot go to the lungs the transferring of oxygen in blood will be affected. If this happens, a person will most likely have difficulty in breathing which may lead to other complications or even death.
  16. 16. ASSESSMENT Directions: Read each question carefully and choose the statement that best answers each question. 1. In the lungs, oxygen is absorbed into the blood. In which part of the lungs does this mainly happen? A. alveoli B. bronchiC. bronchioles D. trachea 2. Which of the following correctly name the parts labeled in the diagram on the right?a. A = alveolus, B = bronchiole b. A = bronchiole, B = trachea c. A = trachea, B = bronchiole d. A = trachea, B = bronchus
  17. 17. 3. Analyze the diagram of the human breathing system on the left. Which of the following is the correct order for air passing through the lungs? a. trachea, bronchi, bronchiole, alveoli b. trachea, alveoli, bronchi, bronchioles c. bronchus, trachea, bronchioles, alveoli d. bronchus, alveoli, trachea, bronchioles
  18. 18. 4.Which process does not occur in the nasal cavity? A. Exchange of gases B.Humidification of inhaled air C. Trapping of large foreign bodies D.Warming of inhaled air 5. Which of the choices below is not a functional process performed by the respiratory system? A. external respiration C. pulmonary ventilation B. pulmonary respiration D. transport of
  19. 19. ASESSMENT • Irregular Puzzle. Fill the grid with appropriate word or words described by the clue. 1. Serve as channel for the airflow through the nose in which the air is warmed, cleaned and moistened. ACROSS: 2.It is also called airsacs; allow the gas exchange in lungs. 3._ _ _ _ _hi, also called bronchial tubes that connect the trachea to the alveoli. DOWN: 1. The organ through which the air enters and is filtered. 2 .It is also called windpipe; a hollow tube that serves as passageway of air into the lungs. 3. The finer subdivisions of the bronchi, hairlike tubes that connect to the alveoli.
