Q

Low resistance area of body:

A
  • Need constant supply of blood

- Even when the heart is relaxed (diastole), there is still a lot of blood flow

18
Q

Describe arterial blood flow wave

A

Spikes (systolic), flows towards organ so wave is above the base line

19
Q

Describe venous wave blood flow

A

Wave below baseline bc blood is leaving organ (exception: Portal vein)

20
Q

Renal arteries have a ___ resistance wave form.

A

Low

  • constant forward blood flow during cardiac cycle
  • kidneys need constant blood supply
21
Q

A pregnant woman has a ___ resistance blood flow to uterus.

A

Low

-uterus needs more blood during pregnancy

22
Q

Celiac axis presents a ___ resistance wave form

A

Low

-mainly the liver and spleen need that blood

23
Q

SMA has a ___ resistance blood flow when pt has not eaten.

A

High

-increase in blood flow after pt eats

24
Q

Resistance ___ I’m SMA after the pt eats

25

26

31
Portal vein normal size is
1.3 cm or 13 mm
32
Prox IVC is more ___ bc of its location to the heart
Pulsatile
33
Distal IVC isn’t as ___ bc of its location away from the heart
Pulsatile
34

4-6mm
40
Distal IVC presents a ___ flow
Phasic
41
IVC is divided into 4 sections:
