Test 2 Flashcards
What is a cusps
Fibrous valves flaps
what is chordae tendinae
Fibrous “parachute strings”
What is the papillary muscle
It pulls the chordae tendinae
What are the characteristics of semilunar valve
- cusps
- support not needed
What do Valves do?
- close to prevent back flow of blood
- AV valve allows blood to move from atria to ventricles
- AV valve closes during ventricular contraction
What is the characteristics of valve prolapse
- Common in the left AV valve

Scarring usually occurs with old age
What is atherosclerosis
Fat deposits usually occurs with bad life decisions
Can be reversible
