Main Parts and Functions of the Respiratory System
Do you know which is your respiratory system? Can you identify the parts of your respiratory system? Here are some clues.
The respiratory system is composed of organs concerned with exchange of gases between the body and environment. The two main jobs of the respiratory system are;
1. To provide the body with oxygen. (The cells of the body need oxygen to break down and to release the energy in food)
2. To remove carbon dioxide from the body. (During the breathing process, carbon dioxide forms as a gaseous waste product.)
Now, based on the respiratory functions, try to identify the parts of the respiratory system of humans. Look at the diagram.
Shown here are the face and the chest of a person, with the lungs. Do you wonder why?
The human respiratory system is composed of the upper and lower respiratory organs.
The upper respiratory organs start with the nose and the mouth. it is combined with the sensory organs of smell and taste. The nasal cavity, the mouth and the oral cavity, and the pharynx are part of the upper respiratory system.
The lower respiratory organs or major organs are the bronchi and the lungs. (Bronchi is the plural form of bronchus).
