1

____ supplies stomach, 30-40% of liver, spleen, and small and large bowel

Arterial system

2

___ supplies the small intestine, cecum, ascending and transverse colon

SMA

3

___ supplies descending/sigmoid colon and most of rectum

IMA

4

Renal arteries are ___ to SMA and ____ to renal veins

Inferior
Posterior

5

Right renal artery is

Longer than the left (further to travel)

6

Left renal artery is

Slightly higher than the right bc of the right lobe of the liver

7

Aorta passes ___ to diaphragm at the ____ and is then termed ____.

Posteriorly
Aortic hiatus
Abdominal aorta

8

SMA is __ cm distal to celiac axis

1cm

9

IMA is ___ cm proximal to bifurcation

4 cm

10

Organs with low resistance vascular beds

Liver
Spleen
Kidneys

11

Organs with high resistance vascular beds

SMA
Iliacs

12

___ renal vein is longer than ___ renal vein.

Left is longer than right

13

PV demonstrates a ___ blood flow

Hepatopetal

14

Veins in the liver with echogenic walls

PV

15

Veins in the liver with hypoechoic walls

Hepatic

16

High resistance area of body:

Don’t need constant supply
Less flow, more diastole

17

Low resistance area of body:

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

18

Describe arterial blood flow wave

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

19

Describe venous wave blood flow

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

20

Renal arteries have a ___ resistance wave form.

Low
-constant forward blood flow during cardiac cycle
-kidneys need constant blood supply

21

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

Low
-uterus needs more blood during pregnancy

22

Celiac axis presents a ___ resistance wave form

Low
-mainly the liver and spleen need that blood

23

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

High

-increase in blood flow after pt eats

24

Resistance ___ I’m SMA after the pt eats

Lowers

25

___ drain the liver

Hepatic veins
-left, right, and middle

26

IVC lies __ to rt kidney and ___ to liver before coursing through the diaphragm

Medial
Posterior

27

Ivc enters into the ___of the heart

Right atrium

28

The portal vein is ___ bc of collagen

Echogenic

29

The PV present a ___ flow

Hepatopetal
Above the baseline

30

IVC should be __-__ I’m size

2.5-3.5 cm or 25 to 35mm

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

Hepatic veins will present a ___ blood flow

Hepatofugal- away from liver
-below baseline

35

Renal veins have a ___ flow.

Phasic

36

Hepatic veins should measure

4-6mm

37

Splenic vein should measure

4-6mm

38

SMV should measure

6-7 mm

39

Renal veins should measure

4-6mm

40

Distal IVC presents a ___ flow

Phasic

41

IVC is divided into 4 sections:

Hepatic, prerenal, renal, and postrenal
