1. The Respiratory System

2. oxygen Our respiratory system is responsible for bringing air into the body, from which we can get oxygen .

3. carbon dioxide It also moves air back out of the body—the exhaled air contains more of our waste gas, carbon dioxide .

4. The parts of the respiratory system are the nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and diaphragm.

5. The human respiratory system moves fresh air into the body while removing waste gases. The Lungs are the main respiratory organs. To provide oxygen to capillaries to oxygenate blood and to sustain life. Oxygen and carbon dioxide are exchanged at the alveoli . To Recap

6. air Let’s follow the journey of a breath of air, starting with the moment you inhale.

7. Air enters the body through the nose and mouth, where it is filtered and warmed. nasal cavity oral cavity pharynx larynx

8. PHARYNX LARYNX The Pharynx, the passageway for both food and air , collects incoming air from the nose and passes it downward to the Larynx, also known as the voice box, found in the lower end of the pharynx that contains the vocal cords.

9. TRACHEA The TRACHEA or wind pipe is the passageway of air from larynx going down to the bronchus or bronchi. A flap of tissue found in trachea called epiglottis .

10. bronchioles alveoli Trachea is divided into two tubes- one for each lung called bronchi , which are passageway of air and from the lungs.

11. Oxygen and carbon dioxide are exchanged at the alveoli. The ALVEOLI or AIR SACS are responsible for the e xchange pf gases such as oxygen and carbon dioxide in the lungs.

12. Oxygen then moves from inside the alveoli across the walls and into the blood. This oxygen is used for respiration by the body’s cells. capillary oxygen red blood cell air moving in and out of the alveolus
