1.
CARDIAC OUTPUT IS...
a)
The number of times the heart beats in one minute.
b)
The amount of blood ejected by the left ventricle per beat.
c)
The amount of blood pumped out of the heart in one minute
d)
Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
2.
STROKE VOLUME IS...
a)
The amount of blood ejected by the left ventricle per beat.
b)
The amount of blood pumped out of the heart in one minute
c)
The number of times the heart beats in one minute.
d)
The blood returning to the heart via the inferior and superior vena cava.
3.
SYSTOLIC BLOOD PRESSURE IS...
a)
During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
b)
Pressure in the arteries when the heart relaxes and ventricles fill with blood.
c)
Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
d)
The number of times the heart beats in one minute.
4.
HEART RATE IS...
a)
During exercise, blood flow is redirected away from the spleen, kidneys, guts and inactive muscles so that working muscles receive a greater % of Q.
b)
The number of times the heart beats in one minute.
c)
The blood returning to the heart via the inferior and superior vena cava.
5.
REDISTRIBUTION OF BLOOD FLOW IS...
a)
During exercise, blood flow is redirected away from the spleen, kidneys, guts and inactive muscles so that working muscles receive a greater % of Q.
b)
Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
c)
During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
6.
BLOOD VOLUME IS...
a)
During aerobic exercise, blood volume increases. Plasma volume increases rapidly in the first 5 minutes of exercise then stabilises.
b)
The number of breaths taken in one minute.
c)
The blood returning to the heart via the inferior and superior vena cava.
d)
During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
7.
VENOUS RETURN IS...
a)
The blood returning to the heart via the inferior and superior vena cava.
b)
The number of breaths taken in one minute.
c)
The blood returning to the heart via the inferior and superior vena cava.
d)
During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
8.
DIASTOLIC BLOOD PRESSURE IS...
a)
Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
b)
The blood returning to the heart via the inferior and superior vena cava.
c)
Pressure in the arteries when the heart relaxes and ventricles fill with blood.
9.
VASOCONSTRICTION IS...
a)
A increase in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
b)
A increase in the diameter of a blood vessel, resulting in a increase in blood flow to the area supplied by the blood vessel.
c)
A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
d)
A decrease in the diameter of a blood vessel, resulting in no change in blood flow to the area supplied by the blood vessel.
10.
VASODIALATION IS...
a)
A increase in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
b)
A increase in the diameter of a blood vessel, resulting in a increase in blood flow to the area supplied by the blood vessel.
c)
A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
d)
A decrease in the diameter of a blood vessel, resulting in no change in blood flow to the area supplied by the blood vessel.

c)
(VO2 )The volume of oxygen that can be taken up and used by the body per minute.
d)
The movement of molecules from an area of higher pressure to one of lower concentration.
12.
