Answer 43

max pressure during ventricular contraction

Question 44

Diastolic (pressure)

Answer 44

minimum pressure with ventricle relaxation

Question 45

Cardiac Output

Answer 45

Volume/minute = stroke volume (times) rate

Question 48

Frank-Starling Law of the heart

Answer 48

Greater venous return, greater ventricular will fill more fully, produces stronger contraction = greater stroke volume and more cardiac output
