Chapter Eleven Flashcards
A vessel that carries blood away from the heart
Artery
Specialized mass of conducting cells located at the atrioventricular junction of the heart
Atrioventricular valves
A chamber of the heart receiving blood from the veins
Atrium
A minute blood vessel connecting arterioles with venules
Capillary
Sequence of events encompassing one complete contraction and relaxation of the atria and ventricles of the heart
Cardiac cycle
The blood volume in liters ejected per minute by the left ventricle
Cardiac output
The cardiac muscle layer of the heart wall
Myocardium
The membranous sac enveloping bundles of muscle fibers
Pericardium
The resistance to blood flow offered by the systemic blood vessels; a measure of the amount of friction encountered by blood
Peripheral resistance
System of blood vessels that carry blood to and from the lungs for gas exchange
Pulmonary circulatory
The rhythmic expansion and recoil of arteries resulting from heart contraction
Pulse
The modified cardiac muscle fibers of the conduction system of the heart
Purkinje fibers
Valves that prevent blood return to the ventricles after contraction
Semilunar valves
Minute artery
Arteriole
System of blood vessels that carries nutrient and oxygen-rich blood to all body organs
Systemic Curculation
