the circulatory system 2

Blood flow is inversely proportional to the total peripheral resistance.

• True

• False

Increased in oxygen delivery during exercise accomplished by _______.

• increased cardiac output

• redistribution of blood flow from in active organs to working muscles

• reduce heart rate

• increase body temperature

An increase in cardiac output during exercise is due to _________.

• increase heart rate

• reduce stroke volume

• increase total peripheral resistance

• reduce blood pressure

During incremental exercise the systolic blood pressure increases, but the diastolic BP remains fairly constant.

• True

• False

At the same oxygen uptake, arm work results in _______.

• higher heart rate

• lower heart rate

• higher stroke volume

• lower blood pressure
