Question 1

Flow =

Answer 1

change in pressure over resistance

Question 2

Pressure difference is the

Answer 2

mean arterial pressure - central venous pressure

Question 3

Arterioles act as the top controlling

Answer 3

resistance (and therefore flow) to each vascular bed

Question 4

Elastic artery size of lumen

Answer 4

wide

eg aorta

Question 5

muscular artery size of lumen

wide

low resistance conduit

Question 6

resistance vessels example

Answer 6

arterioles

Question 7

arterioles size of lumen

Answer 7

narrow

arterioles function

Answer 8

control resistance and therefore flow

allow regional direction of blood flow
