lining of the inside of the heart

22
Q

AtrioVentricular valves (AV)

A

valves between the Atrium and Ventricle

23
Q

semilunar valves

based on antigens A and B located on the outside of the blood cell

25
Q

when A and B blood mixes

A

blood coagulates (clots)

Q

Rh factors (rhesus monkey)

A

Rh+ has antigen Rh- does not

Q

congestive heart failure (CHF)

A

loss of pumping ability

30
Q

fibrillation

A

rapid contraction of either the atria or ventricles

31
Q

endocarditis

A

bacterial infection of the endocardium

32
Q

murmur

A

sound when one of the heart valves does no close properly allowing blood to flow backwards in the heart

33
Q

rheumatic fever

A

throat infection that travels to the heart causing damage to the valves
