Found in stomach and arteries; moves substances through the lumen of these organs
smooth muscle
-
Found in heart muscle.
cardiac muscle
-
When the ventricles contract, blood is prevented from backing up into the atria by the:
atrioventricular valves
-
The "pacemaker" of the electrical conduction system of the heart is the:
SA node
-
Deoxygenated blood (low in oxygen) is found in the:
left pulmonary arteries
-
The first heart sound (lub) is caused by vibrations occuring when the __________ valves close during ventricular ____________ .
atrioventricular;systole
-
The accumulation of soft masses of fatty material beneath the inner lining of arteries is a condition known as ____________ and may lead to a potentially fatal ___________ .
atherosclerosis;thromboembolism
-
Oxygenated blood (high in oxygen) leaves the heart through the
aorta
-
Blood vessels that are one cell thick to allow exchange of material between the blood and tissue.
capillaries
-
Blood vessels which contain valves
veins
-
Blood pressure is highest in these vessels.
arteries
-
Constriction and dilation of these blood vessels help regulate blood pressure
arterioles
-
Highly muscular lower chambers of the heart.
ventricles
-
Muscular wall seperating the right and left sides of the heart.
septum
-
Dissolves thromboembolisms.
t-PA
-
Reduces the ability of platelets to stick together and thus lowers the probability of a heart attack.
aspirin
-

coronary bipass
-
Many copies of the gene for this factor is injected directly into the heart to encourage the growth of new blood vessels.
