1. PARTS & FUNCTION OF RESPIRATORY SYSTEM GIOVANI G. MACARIOLA Teacher III S6LT-IIa-b-1

2. CLASSROOM RULES ( The 5 P’s)

3. Be on time at the beginning of the day and after lunch or recess breaks. Come prepared with supplies and completed assignments. Be kind, polite and courteous to others. Keep your hands and feet to yourself. Be respectful of classmates, teachers and property. Listen to the teacher and classmates, and follow directions. Work hard and always do your best. Be safe. Raise your hand when you would like to speak in class or if you need to leave the classroom for any reason.

4. Based on the video presented earlier, what are the three major part of the Circulatory System? Name them. Explain the function of each part.

5. GROUP ACTIVITY

6. GROUP ACTIVITY GROUP 1 Label the parts and give the functions of each part of the respiratory system using a diagram and a literature (Activity sheet # 1) GROUP 2 Solve a jigsaw/picture puzzle of a human respiratory system, will identify each part and give their functions with the help of a literature. (Activity Sheet # 2)

7. GROUP 3 draw and identify the parts and functions of the human respiratory system. GROUP 4 role play the path of air in the human respiratory system. GROUP 5 make a lung model given some materials to work on.

10. The Respiratory System – is the system of the body that deals with breathing. When we breathe, the body takes in the oxygen that it needs and removes the carbon dioxide that it doesn’t need. Function of Respiratory System

12. PARTS OF THE RESPIRATORY SYSTEM

13. LET’S LEARN MORE

14. What are the part and function of the Respiratory system? Why do we need to know the parts and functions of the Respiratory system? How do you take care the organs of the Respiratory System?

15. LET’S ELABORATE

16. What makes the organs so important to us? How do the organs of the respiratory system work together?

17. Body parts protect one another from harm or injury. The health and condition of the whole body depends upon the health and condition of each body part. This principle also applies to a society of people. Every person is a part of society. The condition of the whole society depends upon the condition of each part. Shouldn’t the parts, therefore, strive to protect one another?

18. LET’S RECALL

19. What are main parts and functions of the respiratory system? How do the organs of the respiratory system work together?

20. TIME FOR EVALUATION

21. Multiple Choice: Read each item carefully. Choose the letter of the correct answer in 30 seconds. READY? LET’S START!

22. Tiny hairs lined inside the nose prepare air for the lungs by. cleaning it drying it moistening it warming it

23. How does the body use the energy released in its cells? to rest the body for making oxygen to lower body temperature. for muscles to move

24. When you exhale, the diaphragm helps air leave the body by expanding the lungs making the chest larger pushing air in the lungs making the chest smaller

25. The body’s cells use oxygen to break sugar into ___________. oxygen and water carbohydrates and water protein and water carbon dioxide and water

26. What happens when you breathe in air? The diaphragm expands and the ribcage contracts. the diaphragm contracts and the ribcage expands. the diaphragm expands and the rib cage collapses. The diaphragm contracts and the ribcage remain the same.

27. Identify the parts of the Respiratory System. nose

30. Remember… Safety First! <<<THANK YOU>>>

31. When you breathe in, air enters the nasal cavity by passing through the nostrils. Hairs within the cavity filter out dust, pollen and other foreign particles before the air passes into the two passages of the internal nasal cavity. Here the air is warmed and moistened before it passes into the nasopharynx. A sticky mucous layer traps smaller foreign particles, which tiny hairs called cilia transport to the pharynx to be swallowed. Nasal Cavity

32. Commonly called the throat, the pharynx is a small tube that measures approximately 10–13 cm from the base of the skull to the level of the sixth cervical vertebra. The muscular pharynx wall is composed of skeletal muscle throughout its length. The funnel-shaped pharynx connects the nasal cavity and mouth to the larynx (air) and oesophagus (food). It is a passageway for food as well as air, so special adaptations are required to prevent choking when food or liquid is swallowed. Pharynx

33. The larynx, or voice box, has rigid walls of muscle and cartilage, contains the vocal cords and connects the pharynx to the trachea. It extends for about 5 cm from the level of the third to sixth vertebra. Larynx

34. The trachea or windpipe denotes the start of the lower respiratory tract. It is about 12 cm long and 2 cm in diameter. It contains rings of cartilage to prevent it from collapsing, and it is flexible. It travels down the neck in front of the esophagus and branches into the right and left bronchi. Trachea

35. The epiglottis is the small flap of cartilage at the back of the tongue which closes the top of the trachea when you swallow to ensure food and drink pass into your stomach and not your lungs. Epiglottis

36. Your lungs are the organ that allows oxygen to be drawn into the body. The paired right and left lungs occupy most of the thoracic cavity and extend down to the diaphragm. They hang suspended in the right and left pleural cavities straddling the heart. The left lung is smaller than the right. Lungs

37. The bronchi branch off the trachea and carry air to the lungs. By the time inhaled air reaches the bronchi, it is warm, clear of most impurities and saturated with water vapour . Bronchi

38. Bronchioles are small airways that extend from the bronchi and connect the bronchi to small clusters of thin-walled air sacs, known as alveoli. Bronchioles are about 1 mm in diameter and are the first airway branches of the respiratory system that do not contain cartilage. Bronchioles

39. In each lung there are approximately 300 million gas-filled alveoli. These are responsible for the transfer of oxygen into the blood and the removal of waste such as carbon dioxide out of the blood. This process of transfer is known as gaseous exchange. Alveoli

40. The diaphragm is a flat muscle that is located beneath the lungs within the thoracic cavity and separates the chest from the abdomen. The diaphragm is one of several components involved in breathing, which is the mechanism of drawing air – including oxygen – into the body (inhalation) and removing gases including carbon dioxide (exhalation).
