Topic 2.2 cardiovascular system

Question 1

composition of blood (4)

Answer 1

red blood cells (Erythrocytes)
white blood cells (Leucocytes)
platelets
plasma

Question 2

cardiac output

Answer 2

stroke volume x heart rate

Question 3

stroke volume

Answer 3

volume of blood pumped out of the left ventricle after a contraction

Question 4

factors affecting cardiac output (3)

Answer 4

1. gender
2. training status
3. age

Question 5

cardiovascular drift (3)

Answer 5

1. increase body temperature (lower heart rate)
2. decrease blood volume from sweating
3. stroke volume decreases as the heart rate increases

Question 6

systolic

Answer 6

force exerted by blood on arterial walls during contraction

Question 7

diastolic

Answer 7

force exerted by blood on arterial walls during relaxation

Question 8

cardiovascular adaptations from endurance training (3)

Answer 8

1. increased left ventricle
2. increased stroke volume
3. lower resting heart rate
