An atheroma develops from
the uncontrolled cell division of simple squamous tissue in the vascular endothelium.
repeated vasospasms.
a thrombus in a vein.
accumulated fatty material, cells, and fibrin in the damaged endothelium of arteries.

persistent chest pain, radiating to the left arm
pallor
rapid, weak pulse
The most common cause of a myocardial infarction is
hypercalcemia.
myocarditis.
atherosclerosis involving an attached thrombus.
a block in the conduction system of the heart.
A myocardial infarction could be confirmed by
high levels of cholesterol and triglycerides in the blood.
elevated C-reactive protein and leukocytosis.
the presence of ventricular hypertrophy.
an EKG and serum isoenzymes released from necrotic tissue.
Congestive heart failure is defined as
the cessation of all cardiac function.
inability of the heart to pump enough blood to meet the metabolic demands of the body.
a low circulating blood volume.
a ventricular septal defect that results in a left-to-right shunt of blood.

sinoatrial node
atrioventricular node
tricuspid and bicuspid valves
One of the body's largest blood vessels that transports blood from the body region below the diaphragm to the heart
superior vena cava
inferior vena cava
pulmonary trunk

This initiates the action potential that causes the heart to beat
Inferior vena cava
Atrioventricular node (AV node)
Superior vena cava
Sinoatrial node (SA node)
These are the smallest blood vessels with the thinnest walls in order to maximize diffusion of nutrients in and out of the interstitial fluid
arteries
veins
capillaries
aorta
Which best explains why capillary walls are so thin?
because they do not need to pump blood
because they are found only in the smallest organs and tissues
because they maximize diffusion of nutrients
because blood only travels through them slowly
Why is coronary circulation necessary?
because blood needs to be pushed throughout the entire body
because the heart itself needs nourishment
because the scalp requires an exceptional amount of nourishment
