What does breathing involve?

Breathing involves the two-step process of inhalation and exhalation. Inhalation is the act of taking in air into the lungs, while exhalation is the act of expelling air from the lungs. These two processes work together to facilitate the exchange of respiratory gases, allowing oxygen to enter the body and carbon dioxide to be eliminated. It is important to note that breathing is a continuous process, with inhalation and exhalation occurring repeatedly in cycles.
