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

A normal thrombocyte count per cubic millimeter of blood is

250,000 to 400,000

4.5 to 5.5 million

List three treatments that can be used to control hypertension

anti-hypertensive drugs, diuretics, limited stress, avoidance of tobacco, low-sodium and or low-fat diet

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

The blood cells that contain hemoglobin are the

erythrocytes

fight infection

Trace a drop of blood through the heart, to the lungs, and back to the heart. Name the blood vessels carrying the blood, the valves, and all chambers of the heart.

inferior and superior vena cava right atrium tricuspid valve right ventricle pulmonary valve pulmonary arteries lungs pulmonary veins left atrium mitral valve left ventricle aortic valve aorta arteries arterioles capillaries body cells venules veins

The chamber of the heart that receives oxygenated blood as it returns from the lungs is the

left arium
