Answer 2

Answer:

As breathing goes on continuously, a sleeping man's chest can be seen going up and down.

Explanation:

• Breathing moves air in and out of the lungs, primarily to expel carbon dioxide and bring in oxygen, and to facilitate gas exchange with the internal environment.
• The main function of respiration is to bring in oxygen and expel carbon dioxide through the movement of the lungs.
• The muscles that control the movement of the lungs are the muscles between the diaphragm (the layer of muscle underneath the lungs) and the ribs.
• Breathing uses chemical and mechanical processes to bring oxygen to every cell in the body and remove carbon dioxide.
• Our bodies require oxygen to generate energy for all life activities.
