factors affecting bp

Question 1

common factors

Answer 1

genetics, activity, stress, body temp, diet, medication

Question 2

what are 4 major factors

Answer 2

cardiac output
arteriolar resistance
vessel elasticity
blood volume

Question 3

4 factors

cardiac output

Answer 3

amount of blood pumped from each ventricle in 1min

Question 4

4 factors

arteriolar resistance

Answer 4

blood encounters resistance when they contact vessel walls. more resistance means more pressure needed to keep blood moving

sources: vessel diameter, blood viscosity, vessel length

Question 5

4 factors

vessel elasticity

Answer 5

healthy artery expands and recoils to absorb shock of systolic pressure

hard arteries=don’t expand=higher pressure=weaker

Question 6

4 factors

blood volume

Answer 6

total amount of fluid circulating in the system

reduced blood volume (from sweating) decreases bp
increase blood volume (water retention from high salt intake) increases bp
