Test 2 - systemic perfusion

Question 1

hemodynamic steady state

Answer 1

Q_out = Q_in

upstream blood pressure will “always settle” at the value that causes the rate of outflow to become equal to the rate of inflow

Question 2

if flow in does not equal flow out…

what needs to increase in order for the Q’s to equal out?

Answer 2

P_up needs to increase

Question 3

ohm’s law

Answer 3

arterial blood pressure results from the continuous interaction between cardiac output and peripheral resistance

Question 4

cumulative rate of discharge from all the arteries throughout the body

Question 5

responsive to sudden changes in upstream arterial pressure

Answer 5

myogenic autoregulation

Question 6

reponsive to changes in localized metabolism

Answer 6

metabolic autoregulation

Question 7

regional arteriolar input resistance is adjusted by ______ and ____

Answer 7

metabolic

and

myogenic autoregulation

Question 8

peripheral resistance is maintained and regulated by _________

Answer 8

central reflex (baroreflex)

which controls cardiac output

Question 9

the overall compliance of the venous system (70% of total blood volume) is 20x ____ than arteriolar blood

Answer 9

greater

Question 10

flow of blood from the distal veins into the central veins and right atrium

Answer 10

venous return
