The respiratory surface must be thin, permeable, moist, have large surface area, highly vascular and in direct contact with source of oxygen.
The process of breathing involves taking in oxygen-rich air and giving out carbon dioxide-rich air. This entire process occurs through the action of the various organs of the respiratory system.
We take in air through our nostrils, and when we breathe in, air passes through our nostrils into the nasal cavity.
Air then reaches the lungs, which are located in the chest cavity. The actual mechanism of breathing involves the movement of the rib cage and the diaphragm located around and at the base of the chest cavity respectively.
