Answer:

Keeping the alveoli open and for constant gas exchange.

Explanation:

After maximum expiration of the air in the lungs, there remains still some air called the residual volume. This is because the alveoli, the smallest sacs in the lungs which take part in the exchange of gases between the lungs and the bloodstream, need to stay inflated and open. This also ensures that the gas exchange is continuous between breaths which is really important. I hope this answer helps.

Muscles help keep blood flowing normally through the body. How do muscles accomplish this task?
bezimeni [28]

Answer:

Option A, by having a constant supply of blood

Explanation:

Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed.  During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.

Hence, option A is correct
