Chapter 7: Cardiovascular System

Question 1

Cardiac Output (CO)

equation

Answer 1

CO = stroke volume x heart rate

Question 2

cardiac output

definition

Answer 2

the amount of blood pumped out of the left ventricle in 1 minute

Question 3

Stroke volume

definition

Answer 3

the change in left ventricle volume before and after contraction of the heart (amount of blood pumped out in a single heartbeat)

Question 4

stroke volume

equation

Answer 4

EDV = end diastolic volume
ESV = end systolic volume

Question 5

systole

Answer 5

ventricular contraction/ejection

heart muscles contract

Question 6

diastole

Answer 6

ventricular filling

heart muscles are relaxed
