ANATOMY

Detailed explanation-1: -The respiratory system acts as the support system for the muscular system. The respiratory system brings oxygen into the body for the muscular system to use.

Detailed explanation-2: -Which best explains how the muscular system relies on the respiratory system? The respiratory system brings oxygen into the body for the muscular system to use and takes carbon dioxide out.

Detailed explanation-3: -However, the muscular system requires the oxygen that is brought in from the respiratory system to act as the final electron acceptor in oxidative phosphorylation. Without O2, the muscles would be unable to generate enough ATP to continue contracting and functioning properly in general.

Detailed explanation-4: -Oxygen gets into the blood through tiny blood vessels around the alveoli. Red blood cells pick up the oxygen and deliver it to the body’s cells.

Detailed explanation-5: -The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
