1.what does each of the part represent in the respiratory system?​

In the respiratory system:

1. **Nose and Mouth:** Act as entry points for air, helping filter and humidify it.

2. **Trachea (Windpipe):** Transports air from the nose and mouth to the lungs.

3. **Bronchi:** Branches of the trachea that lead air into the lungs.

4. **Lungs:** Organs where gas exchange occurs. Oxygen is taken in, and carbon dioxide is expelled.

5. **Bronchioles:** Smaller airways within the lungs that further distribute air.

6. **Alveoli:** Tiny air sacs within the lungs where oxygen and carbon dioxide exchange takes place.

7. **Diaphragm:** Muscle beneath the lungs that contracts and relaxes, aiding in breathing.
