Travis is taking a long run, and his muscle tissue needs more oxygen. He is breathing heavily and taking in a lot of oxygen. How
does this exercise affect circulation?

B. Travis's heart pumps more slowly to give the blood cells time to pick up the oxygen and drop it off at the tissues.

C. Travis's coronary arteries become blocked, so blood travels to other muscles, where it is necessary.

D. Travis's heart starts angiogenesis so that he has more vessels to transport blood to the tissues.
