Arterial System

Question 1

multi branches elastic conduit set into oscillation by

Answer 1

each beat of the heart

Question 2

each beat pumps about ____ ml of blood into the AO causing a ______

Answer 2

70

blood pressure pulse

Question 3

cardiac contraction begins

Answer 3

pressure in the left ventricle rises rapidly
left ventricle pressure exceeds that in the ao
ao valves opens, blood is ejected, BP rises

Question 4

increased heart rate delivers an increased

Answer 4

blood volume

Question 5

what plays a role in the movement of blood throughout the vascular system

Answer 5

pt cardiac status

Question 6

heart pump

Answer 6

generates the pressure to move the blood

results in a pressure wave (energy wave) that travels rapidly through the system, demonstrating a gradual transformation as it travels distally

Question 7

Order which blood travels

Answer 7

1. Left ventricle
2. ao
3. large arteries
4. arterioles
5. capillaries
6. venules
7. large v
8. vena cava
9. rt atrium

Question 8

what action of the heart results in high volume of blood in arteries to maintain a high pressure gradient between the arteries and vein

Answer 8

pumping action

Question 9

what determines amount of blood entering arterial system; arterial pressure and total peripheral resistance, determines amount that leaves it

Answer 9

cardiac output

Question 10

pressure is lower at the heart T/F

Answer 10

false, its greater and gradually decreases as the blood moves further away

Question 11

what is needed to maintain blood flow

Answer 11

pressure difference
