Answer 1

A. The human body is obviously well equipped to extract oxygen from inhaled air and deliver that oxygen to all cells in the body, including muscles. ... At the same time, carbon dioxide that was produced by muscles and other cells leaves the blood, passing across the lung membranes to be exhaled from the body

Answer 2

Answer:

The air sacs absorb more oxygen during vigorous exercise.

Explanation:

Function of respiratory system is to carry out gaseous exchange to makes the blood rich in oxygen. Musculoskeletal system is involved in movement of body and needs oxygenated blood to drive the muscle contraction and body movements. Musculoskeletal system needs increased oxygen supply during vigorous physical activity to support the movement which in turn is fulfilled by increased absorption of oxygen by air sacs.
