Which term describes the inhalation and exhalation of air?

Explanation:
Breathing, called respiration, is the inhaling and exhaling of air. It involves bringing oxygen into the lungs and releasing carbon dioxide as a waste product, with gas exchange occurring there. Digestion refers to breaking down food in the digestive system, circulation means moving blood through the heart and vessels, and metabolism covers all the chemical reactions that convert nutrients into energy and building blocks for cells. Because inhaling and exhaling describe the breathing process and gas exchange, respiration is the best term.
