Question 4

lowest point of pressure induced by the relaxation of ventricle

Answer 4

diastole

Question 5

difference between systole and diastole (normal range: 30-50)

the average arterial pressure during a single cardiac cycle

Answer 6

mean arterial pressure

Question 7

formula for MAP

Answer 7

MAP = (2 x diastolic) + systolic / 3

Question 8

regulator of blood volume, electrolyte balance, and systemic vascular resistance

Answer 13

RAAS renin-angiotensin-aldosterone system

Question 14

cardiac output formula

Answer 14

CO = SV x HR
