Arteries: all branches are from ...

Veins: all drain to either
1. ... (from body wall)
or
2. ... (from G.I. tract)

Front 5

Unpaired visceral:

Celiac trunk
1. Supplies the “...”: lower esophagus to 2nd part of duodenum

2. Also supplies the ... (not foregut)

3. Branches:
a. ...: lesser curvature of stomach
b. ...:
(1) spleen
(2) fundus of stomach
(3) left greater curvature of stomach
(4) neck, body & tail of pancreas
c. Common hepatic:
(1) ...:
- proximal duodenum
- head of pancreas
- right greater curvature of stomach
(2) ...:
- right gastric (lesser curvature of stomach)
- left hepatic (liver)
- right hepatic (liver)
- cystic (gallbladder)

Front 6

Superior Mesenteric Artery (SMA)

1. Supplies the “...”: 2nd part of duodenum to ... 1/3 of transverse colon

2. Branches:
a. duodenum, jejunum, ileum: all on left side of SMA
b. ...: distal ileum & 1st part of colon (including cecum & appendix)
c. ...: ascending colon
d. ...: transverse colon
e. ... (of Drummond): “connections between named arteries; along the “margin” of the large intestine

Back 6

midgut
distal
ileocolic a
right colic
middle colic
marginal artery

Front 7

... end artery - if you lose the artery, the tissue dies.

... end artery
-has connection
-anastomosis too small; tissue will die

Front 8

Inferior Mesenteric Artery

1. Supplies the “...”: distal 1/3 of transverse colon to the upper rectum

2. Branches:
a. ...: descending colon
b. ... (3-5): sigmoid colon
c. ...: superior rectum

Back 8

hindgut
left colic a
sigmoidal
superior rectal a

Front 9

paired visceral arteries:

1. ... adrenal aa. (note: ... & ... adrenal aa. exist but do not arise from aorta)

2. ... aa. (kidney)

3. ... aa.
a. testicular (male) or ovarian (female)
b. aa. & vv. at this vertebral level due to developmental site of origin

Arteries of abdominal wall:

Paired:
1. Inferior ... a.
2. ... aa. (4 pairs): similar to posterior intercostals in origin & distribution

Unpaired:
3. Median ... a.

Front 12

Hepatic Portal Vein (from gut that is supplied by unpaired visceral arteries):

1. Receives all venous blood from foregut (including ...), midgut, and hindgut

2. Digestive tract: lower esophagus to upper rectum

3. ... glands: gallbladder, pancreas

4. HPV formed by joining of splenic and ... veins

5. Inferior mesenteric vein --> ... v.

6. HPV --> liver sinusoids --> hepatic veins --> IVC just below diaphragm

Innervation of abdomen:

Abdominal walls: skeletal muscle; ... innervation (e.g. intercostal nn. T7-T11; T12; L1)

Abdominal viscera: ...
1. Sympathetic: ... (T1-L2)
2. Parasympathetic:
a. ... (CN#): down to “splenic flexure”
b. S2-S4: distal 1/3 to “splenic flexure”; pelvis
