Question 8

pericarditis

Answer 8

fibrous inflammation outside the pericardium that forms fibrin strands from fibrinogen that irritates the heart when it moves

Question 9

Endocarditis __% of the time involves the valves of the heart

Answer 9

80%

Question 10

made of a dense fibrous layer with fluid for movement

Answer 10

pericardium

Question 11

made with dense fibrous layer that is continuous with the valves of the heart

Answer 11

endocardium

Question 12

what causes regurgitation/ insufficient valves?

Answer 12

with damage/irritation the fibrous tissue that makes up the valves is replaced with connective tissue, this tightens and strings the cuffs. This causes incomplete closer of the valves resulting in back flow.

Question 13

insufficient valves/regurgitation can cause

Answer 13

hypertrophy of the (left) atrium (mitral)

Answer 14

mitral

Answer 19

stats of blood in the lungs, end up drowning due to Pulmonary edema

Question 20

what is the appropriate treatment for when the LV dilates and causes Aortic valve issues?

Answer 20

valve replacement
