Quizplus · Accepted Answer

During exercise, vasodilation occurs at the active skeletal muscles to increase blood flow and oxygen delivery. Venous return also increases to maintain cardiac output and provide nutrients to the working muscles. Cardiac output and stroke volume both increase to meet the increased demands of the body during exercise. Tissue perfusion to the digestive system decreases due to the redirection of blood flow to the active muscles. Therefore, all of the answers are correct.
