Respiratory System: Organs, Facts, Anatomy & Function
What is the respiratory system? Your respiratory system is the organs and structures in your body that allow you to breathe. It includes your lungs, nose, mouth and the tubelike structures (airways) that connect them. You also have muscles and blood vessels that support your respiratory system, and ribs to protect it. These parts work together to bring oxygen into your body when you inhale and ...
Respiratory system - Wikipedia
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. In land animals, the respiratory surface is internalized as linings of the lungs. [1] Gas exchange in the lungs occurs in millions of small air sacs. In mammals and reptiles, these are called alveoli, and in ...
