Question

Many factors affect blood flow and delivery to the organs of the body. Which of the following factors causes the greatest increase in blood flow?

(A) Vasoconstriction
(B) Decreasing vessel length
(C) Vasodilation
(D) Decreasing blood viscosity

Answer 1

(C) Vasodilation

Step-by-step explanation:

Vasodilation causes the greatest increase in blood flow. When blood vessels dilate, the diameter of the vessel increases, which leads to a decrease in resistance to blood flow. This results in an increased blood flow to the organs of the body.
