Question

Name the mechanism of moving air in and out of body

Answer 1

PLEASE MARK MY ANSWER AS BRAINLIEST

Respiration begins with ventilation, the process of moving air into and out of the lungs. Gas exchange in the lungs takes place across the thin walls of pulmonary arteries in tiny air sacs called alveoli. Oxygenated blood is transported by the circulatory system from lungs to tissues throughout the body.
