Answer 1

during inhalation our chest cavity will increase.

Answer 2

Answer:

During inhalation our chest cavity will increase

Explanation:

When you breathe in, or inhale, your diaphragm contracts and moves downward. A large, muscular sheet called diaphragm forms the floor of the chest cavity. Breathing involves the movement of the diaphragm and the rib cage. During inhalation, ribs move up and outwards and diaphragm moves down. This movement increases space in our chest cavity and air rushes into the lungs.
