cardiac output

Question 1

cardiac output

Answer 1

amount of blood pumped from each ventricle in 1min

Question 2

heart rate

Answer 2

beats per minute

avg: 72-75bpm

Question 3

stroke volume

Answer 3

amount of blood forced out with each heartbeat

avg: 70mL

determined by how easily the heart fills with blood and how readily blood is emptied from the heart (ventricular contraction strength)

Question 4

formula

Answer 4

heart rate x stroke volume

Question 5

how does cardiac output relate to cardiovascular fitness

Answer 5

during exercise, cardiac output increases due to the increase in sv, your heart is beating faster and stronger to provide oxygen to your body cells. regular cardiovascular fitness strengthens your ventricular contraction. therefore, your heart will be able to pump more blood per beat at rest and in exercise. this strengthens and reduces strain on your heart
