• aortic valves close

• atria contract

• aortic valves open

• the lungs inflate

A bypass graft may be performed on a person that has:

• a blockage of the coronary artery

• a leaking heart valve

• heart murmur

• hypertension

Vessels that supply blood to the heart itself are called:

• coronary arteries & veins

• pulmonary arteries & veins

• bicuspid

• brachiocephalic arteries & veins

A stroke can occur when a blood vessel in the brain:

• is broken

• is blocked

• both a & b

• neither a nor b

Small vessels that are the site of oxygen and nutrient exchange with body tissues are called:

• capillaries
• purkinje fibers

• sphincters

• venules

These structures hold the heart valves in place (like tent lines or strings):

• chordae tendineae

• visceral pericardium

• interventricular septum

• myocardium

• echocardiogram

• stethoscope

• angiogram
