question 8

Multiple Choice

Which of the following factors is most important in matching the blood flow through a specific tissue with the metabolic needs of that tissue?

• B) parasympathetically induced vasodilation of the capillaries within a tissue allows more blood to flow into the tissue.
• C) local changes within a tissue resulting from increased metabolic activity can produce local arteriolar vasodilation to allow more blood to flow into the tissue.
• D) widespread venous vasoconstriction allows blood to dam up at the tissue level.
• E) the amount of blood flowing through each tissue remains constant through reflex controls to ensure that metabolic needs are continuously met.
