Human Respiratory System

When we inhale, we breathe in oxygen and breathe out carbon dioxide. The exchange of gases is important for metabolic exercises and can be viewed as a chemical procedure.

This respiration process is completed by an arrangement of organs known as the Respiratory System, and the human respiratory framework does the work of respiration in humans.
