Question

which of the following physiological effects occurs as a result of increased exercise? a. the bodys blood pressure decreases throughout the body b. the blood flow is directed towards the large organs c. the levels of oxygen in the body decreases d. the volume of blood pumped by the heart increases please select the best answer from the choices provided.

Explanation:

When exercise increases, the body needs more oxygen and nutrients. The heart responds by increasing the volume of blood it pumps (cardiac output) to meet the heightened demands. Blood pressure generally increases during exercise, not decreases. Blood flow is redirected to working muscles, not just large organs. Oxygen levels in the body don't decrease overall as the respiratory system also adapts to take in more oxygen.

Answer:

D. the volume of blood pumped by the heart increases
