Question

what changes take place in the chest cavity and diaphragm during breathing​

Answer 1

Explanation:

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.

Answer 2

Answer:

During inhalation, the lungs expand with air and oxygen diffuses across the lung's surface, entering the bloodstream. During exhalation, the lungs expel air and lung volume decreases.
