B)False
14
Both the AV (atrioventricular) and SL (semilunar) valves are closed during heart diastole.
A)True
B)False
15

A)True
B)False
16
Stimulation of the heart by the parasympathetic division of the autonomic nervous system causes the heartbeat to slow down.
A)True

The umbilical arteries carry oxygen rich blood to the fetus.
A)True
B)False
30

A)True
B)False
