Physiology Quiz - Cardiovascular Physiology - Part 2
The cardiovascular system is composed of the heart and blood vessels. The basic function of the heart is to pump blood through the blood vessels. The basic function of the blood vessels is to serve as conduits to carry blood away from the heart to the tissues, and to return blood from the tissues back to heart. Test your basic knowledge of cardiovascular physiology by taking this simple quiz.
(1) Of the conductive tissues of the heart, only these cells can directly stimulate cardiac myocytes to contract:
(2) These conductive fibers of the heart originate in the atrioventricular (AV) node and pass through the cardiac skeleton (thick connective tissue that separates the atria and the ventricles):
(3) In an individual at rest, approximately this percentage of total blood volume can be found in the venous system:
(4) In an individual at rest, approximately this percentage of total blood volume can be found in all capillaries:
(5) Which of the following is true of ventricular diastole?
