Question 10

which valves are called semilunar valves?

Answer 10

Aortic + pulmonary

Question 11

Which valves prevent the flow of high pressure blood in ventricles into atria during contraction?

Answer 11

tricuspid+ bicuspid valves( inlet valves)

Question 12

Which valves prevents the backflow of blood from arteries to ventricles?

Answer 12

aortic and pulmonary valves( outlet valves)

Question 13

what are papillary muscles and what is their function?

Answer 13

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction)
