Respiratory System
History of Flávia Rosa - Rio Grande do Sul, Brasil
It is responsible for supplying oxygen to the body and eliminating carbon dioxide, a waste product produced by cells.
Components:
Nose and Nasal Cavity: Where the air is filtered, warmed and humidified.
Pharynx: Common passage for air and food.
Larynx: Contains the vocal cords and connects the pharynx to the trachea.
Trachea: Channel that carries air to the lungs.
Bronchi: Branches of the trachea that carry air to the lungs.
Lungs: Organs responsible for gas exchange (oxygen enters and carbon dioxide leaves).
Alveoli: Small structures in the lungs where gas exchange occurs (oxygen for the blood and carbon dioxide for the air).
Respiratory Process:
Inspiration: Air enters the lungs, carrying oxygen.
Gas Exchange: In the alveoli, oxygen is exchanged for carbon dioxide, which is transported to be eliminated.
Exhalation: Carbon dioxide is expelled out of the body.
