Q

What is the atrioventricular valve?

A

16
Q

What is the importance of valves through the venus system?

A

prevent backflow since there is not contraction in veins to push blood towards the heart other than skeletal muscle

17
Q

What are the two periods of the cardiac cycle?

A

diastole
systole

18
Q

What is diastole?

A

when the ventricles are relaxed and blood can flow from the atria into ventricle

19
Q

What is a basic overview of systole?

A

when the ventricles contract, AV valves shut, semilunar valves open, and blood is pumped into the aorta and pulmonary artery

20
Q

What does the “lub” sound represent?

A

closure of the AV valves at the beginning of systole

21
Q

What does the “dup” sound represent?

A

closure of the semilunar valves at the end of systole
