How do i breathe?

  1. 1. THE HUMAN ORGAN SYSTEM
  2. 2. BREATHING EXERCISE https://www.youtube.com/watch?v=b0FZlT3Uk30
  3. 3. HOW WERE YOU ABLE TO DO THE BREATHING EXERCISE?
  4. 4. THE HUMAN ORGAN SYSTEM RESPIRATORY SYSTEM
  5. 5. IF YOU ARE GOING TO DEDICATE A SONG TO YOUR RESPIRATORY SYSTEM, WHAT WOULD IT BE AND WHY?
  6. 6. HOW DO I BREATHE WITHOUT YOU? Play the Song How Do I Live by LeAnn Rimes
  7. 7. WHAT CAUSES THE AIR TO GO IN AND OUT OF YOUR BODY?
  8. 8. HOW DOES IT HAPPEN?
  9. 9. IDENTIFY THE PARTS Alveoli Nose Bronchioles Nasal passage Trachea Bronchi Nose Alveoli Bronchioles Nasal passage Trachea Bronchi
  10. 10. IS THERE ANY OTHER PARTS NOT MENTIONED?
  11. 11. AMONG THE PARTS YOU HAVE MENTIONED, WHICH PART DOES AIR DO NOT PASS THROUGH?
  12. 12. WHAT DO YOU THINK IS ITS PURPOSE?
  13. 13. LET’S INVESTIGATE! The BREATHING MECHANISM
  14. 14. ACTIVITY: THE BOTTLED BALLOON Objectives: •Explain how the lungs work. •Describe how the movement of the diaphragm helps the air go in and out of the lungs.
  15. 15. ACTIVITY: THE BOTTLED BALLOON Materials: •1 big plastic bottle cut in half •3 balloons (1 big, 2 small) •1 -2 sturdy straw •1 pair of scissors •5 rubber bands/tape/clay
  16. 16. ACTIVITY: THE BOTTLED BALLOON Procedure: • Using a pair of scissors, cut the bottom out of the 2-liter plastic bottle. • Stick the two straws through the two holes of the bottle • Place one balloon on the end of each straw, and secure them with rubber bands/tape, as shown in the figure in your activity sheet.
  17. 17. ACTIVITY: THE BOTTLED BALLOON Procedure: • Stick the balloon ends of the straws through the bottle opening and seal the mouth of the bottle with use of a tape or clay. • Stretch out the larger balloon and place it over the open bottom of the bottle. Secure it as tightly as possible. Refer to the diagram in your activity sheet.
  18. 18. ACTIVITY: THE BOTTLED BALLOON Procedure: • Pull the larger balloon down; that is, away from the bottle, in order to blow up the two small balloons. • Push the larger balloon towards the bottle in order to let the air out of the two small balloons. • Write down 2-3 observations.
  19. 19. ACTIVITY: THE BOTTLED BALLOON Procedure: • Label the diagram of the lung model by writing the represented organ in the model. • Answer the Guide Questions.
  20. 20. GUIDE QUESTIONS Q1. What does each part of the constructed lung model represent? Q2. What happens as you pull down the balloon at the bottom of the model? Q3. What happens as you push up the balloon? Q4. How does the movement of the diaphragm cause the air to go in and out of the lungs? Q5. What might happen if you prick the balloon? clog the ballon inside?
  21. 21. COMPARING THE STRUCTURE TRACHEA BRONCHI BRONCHIOLES ALVEOLI
  22. 22. COMPARING THE STRUCTURE NASAL PASSAGE BRONCHI LUNGS DIAPHRAGM
  23. 23. SUM IT UP! ORGAN Inhalation (air enters) Exhalation (air exits) LUNGS DIAPHRAGM
  24. 24. SUM IT UP! ORGAN Inhalation (air enters) Exhalation (air exits) LUNGS EXPANDS DIAPHRAGM
  25. 25. SUM IT UP! ORGAN Inhalation (air enters) Exhalation (air exits) LUNGS EXPANDS DIAPHRAGM CONTRACTS
  26. 26. SUM IT UP! ORGAN Inhalation (air enters) Exhalation (air exits) LUNGS EXPANDS CONTRACTS DIAPHRAGM CONTRACTS
  27. 27. SUM IT UP! ORGAN Inhalation (air enters) Exhalation (air exits) LUNGS EXPANDS CONTRACTS DIAPHRAGM CONTRACTS RELAXES
  28. 28. HOW ABOUT THIS? Obstruct some parts of the lung model. Reflect on how it affects the breathing mechanism. DO THE NEXT ACTIVITY!
  29. 29. ACTIVITY: POSTER MAKING Create a poster on the importance of a functional respiratory system.
  30. 30. RUBRIC
  31. 31. You will be required to upload your poster/meme/gif in your social media accounts and reflect on the reactions of your peers in the digital world. Write a reflection about it in your journal/ntbk. You may consider answering the following questions. 1. How were you able to show the importance of a working/functional respiratory? 2. How were you able to promote a healthy lifestyle among your peers? 3. Do you think your work will be an effective tool in making your peers be conscious about their lifestyle? Why? 4. How will you elevate the call against unhealthy lifestyle among the youth? EXTENDED ACTIVITY
  32. 32. EXTENDED ACTIVITY On your peers’ reaction to your post. 1.How did your peers react to your post? 2.How did you react or feel about your peers’ thoughts regarding your post? 3.What are some of the positive feedbacks you get from your peers? 4.What are the negative feedbacks you get from your peers? 5.Do you think you made an impact to other people’s lives with your post? Describe how were you able to affect them through your post

  37. 37. QUIZ 4. How does the movement of the diaphragm cause air to go in and out of the lungs? A. Movement of the diaphragm affects the air pressure inside the chest B. By either decreasing or increasing the space of the chest cavity allowing air to go in and out of the lungs C.Both a and b D.Neither a nor b
  38. 38. QUIZ 5. When you hold your breath, which of the following first leads to the urge to breathe? A.falling CO2 B.falling O2 C.rising CO2 D.rising pH of the blood
