The best statement that provides evidence of the interaction between the muscular system and the respiratory system is:
A. The diaphragm’s movement downward to draw air into the lungs shows how muscles are necessary to bring air into the body.
This statement clearly indicates how a muscle (the diaphragm) plays a crucial role in the process of breathing, illustrating the direct interaction between the muscular and respiratory systems necessary for life processes such as respiration.
