SHORT ANSWER
DIF: Bloom's Level B
TOP: 34-2
DIF: III
OBJ: 35.1.3
36. ANS:
The pacemaker generates an electrical impulse that spreads over both atria, signaling the two atria to contract
at almost the same time. It also triggers cells at the base of the right atrium to send an electrical impulse over
the ventricles.
PTS: 1
DIF: Bloom's Level B
REF: 995
NAT: LS_5d
TOP: 34-2
37. ANS:
When the ventricles contract, blood pressure rises sharply. This high pressure is called systolic pressure. As
the ventricles relax, blood pressure drops; the lowest pressure occurs just before the ventricles contract again
and is called diastolic pressure.

38. ANS:
Atria only have to pump blood to the ventricles, while ventricles have to pump blood to the lungs or to the
rest of the body.
