Explanation:

1. Nasal Cavity /Nose

-

The nasal cavity functions to humidify, warm, filter, and act as a conduit for inspired air, as well as protect the respiratory tract through the use of the mucociliary system.

2. Pharynx

-

is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.

3. Larynx

- serves to protect the lower airways, facilitates respiration, and plays a key role in phonation. In humans the protective and respiratory functions are compromised in favor of its phonatory function.

4. Trachea

-

trachea's main function is to carry air in and out of your lungs. Because it's a stiff, flexible tube, it provides a reliable pathway for oxygen to enter your body.

5. Alveoli

-

The main function of the alveoli is storage of air for a shorter period which permits absorption of oxygen into the blood. The gaseous exchange of oxygen and carbon dioxide typically takes place in the alveoli.

6. Lungs

-

Warms air to match your body temperature and moisturizes it to the humidity level your body needs.Delivers oxygen to the cells in your body.Removes waste gases, including carbon dioxide, from the body when you exhale.

7. Diaphragm

-

The diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity.

8. Epiglottis

-

Closing the laryngeal inlet prior to swallowing in order to prevent the food and liquid accessing the airways
