Answer:
When we exercise the blood capillaries dilate because of the removal of waste products like carbon dioxide from muscles during exercise.
The dilated blood vessels results in the increased blood flow and increased blood flow leads to the delivering of more amount of oxygen to the body muscles and cells during the exercise.
So increased blood flow is necessary for the removal of waste products like carbon dioxide and lactic acid generated during exercise and to deliver the appropriate amount of oxygen to muscles to function properly.
The alveoli is where the oxygen moves out of the lungs and into the blood. At the same time carbon dioxide moves out of the blood and into the lungs to be exhaled.
