Question 15

Myocardium

Answer 15

Answer 16

Inner most layer of the heart, thin smooth layer of epithelium and connective tissue that lines the hearts inner chambers, valves, chord tendinae, and papillary muscles

Question 17

Answer 18

Pumps blood the body

Question 19

Veins

Answer 19

Capitance vessels that carry deoxygenated blood from the body to the right side of the heart

Question 20

Tricuspid Valve

Answer 20

Valve between right atria and right ventricle that has 2 separate cusps or flaps

Question 21

Mitral Valve (bicuspid)

Answer 21

Valve that separates left atria from left ventricle and has 2 cusps.

Question 22

Paul Zoll pioneered the AC Defibrillator in what year? Why was it rejected?

Answer 22

1956, rejected due to tissue damage it caused

Question 23

Papillary Muscles

Answer 23

Muscles attached to the chordae tendinae of the heart valves and the ventricular muscle of the heart

Question 24

Chordae Tendinae

Answer 24

Thin strands of fibrous connective tissue that extends from AV valves to the papillary muscles that prevent the AV valves from bulging back into the atria during ventricular contraction
