The human respiratory system consists of trachea, bronchi, bronchioles, alveoli, and pleura.
Human breathing begins with inspiration where the diaphragm decreases and the intercostal muscles open the thoracic cavity.
In inspiration, the volume of air in the lungs increases and the air pressure in the lungs decreases.
In expiration, air pressure in the lungs increases and the volume of air in the lungs decreases.
The process is repeated to maintain oxygen levels in the blood.
The process of human breathing also produces carbon dioxide gas released through expiration.
The main function of the respiratory system is to provide oxygen into the body and remove carbon dioxide gas out.
Red blood cells carry oxygen absorbed by the alveoli throughout the body.
Red blood cells also take carbon dioxide gas from the whole body and bring it back to the alveoli.
The respiratory system also plays a role in sound production. Diaphragm muscles and intercostal muscles help in the production of sound produced from the larynx.
