The underlying goal of the body's cardiovascular control mechanisms is to ensure that all tissues receive which of the following?
 
  a. Blood flow according to their mass
  b. Blood flow according to their size
  c. Equivalent amounts of blood flow
  d. Perfusion according to their metabolic needs

Question 2

During blood loss due to hemorrhage, perfusing pressures can be kept near normal until the vol-ume loss overwhelms the system. Why is this so?
 
  a. Arteries constrict, increasing vascular re-sistance.
  b. Arterioles dilate, decreasing vascular ca-pacity.
  c. Muscle vessels dilate, increasing vascular capacity.
  d. Venules constrict, decreasing vascular ca-pacity.

Answer to Question 1

ANS: D
The goal is to maintain adequate perfusion to all tissues according to their needs.

Answer to Question 2

ANS: D
When blood loss occurs, as with hemorrhage, system capacity is decreased by constricting the venous vessels. Thus, perfusing pressures can be kept near normal until the volume loss over-whelms the system.
