true
(T/F?) The smallest branches if arteries are called arterioles
true
Dilated, swollen veins that have lost elasticity and cause stasis, or decreased blood flow, are called
varicose
The blood vessels that contain valves to prevent blood from flowing in a backward direction are the
veins
The valve between the left atrium and left ventricle that prevents blood from flowing back into the left atrium is the
mitral valve
The muscle layer of the heart is the
myocardium

The largest artery in the body is the
aorta
The blood vessels that are more muscular and elastic than the other blood vessels are the
arteries
The blood vessels that carry blood away from the heart are the
arteries
What is the disease that occurs when fatty plaques are deposited on the walls of arteries?
artherosclerosis
