Cardiovascular Physiology - Part 4
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)   During the plateau phase of the cardiac action potential, membrane permeability to K+ (pK) is lower than its resting value.
(2)   Venous blood is commonly referred to as deoxygenated blood because its oxygen content is zero.
(3)   Venous blood is commonly referred to as deoxygenated blood because its oxygen content is lower than the oxygen content of arterial blood.
(4)   Blood oxygen content is higher in the pulmonary artery than in the pulmonary vein.
(5)   Blood oxygen content is lower in the pulmonary artery than in the pulmonary vein.
