Mark the following statements as true or false. If a statement is false, correct it to make a true statement. a. Arterioles reflexively dilate when blood pressure increases. b. Increased concentrations of carbon dioxide and hydrogen ions and a decreased concentration of oxygen in the interstitial fluid cause local arteriolar constriction. c. Tissue perfusion to the heart decreases during systole and increases during diastole. d. The increase in tissue perfusion in skeletal muscle that occurs during exercise is known as hyperemia. e. The sympathetic nervous system causes vasodilation in the skin when body temperature decreases.

Arterioles reflexively dilate when blood pressure increases. This statement is true. When blood pressure increases, arterioles reflexively dilate to help lower the pressure and maintain proper blood flow. b. Increased concentrations of carbon dioxide and Show more…
