Q

What are the branches of the superior mesenteric artery?

A

Inferior pancreaticoduodenal artery
Middle colic artery
Jejunal arteries
Right colic artery
Ileocolic artery
Ileal arteries

19
Q

What are the differences between the jejunal arteries and the ileal arteries?

A

Jejunal have less complex arcades, with extremely long vasa recta.

Ileal have complex arcades and short vasa recta.

20
Q

What is the appendicular artery a branch of?

A

The ileocolic artery

21
Q

What is the marginal artery (of drummond)?

A

Anastamoses between the left and middle colic arteries.
It connects the superior and inferior mesenteric arteries as a result.
It is found primarily at the splenic flexture, supplying blood to the transverse and descending colon.

22
Q

What composes the hindgut?

A

Distal half of transverse colon
Descending colon
Sigmoid colon
Proximal 1/3 of rectum

colon colon colon rectum

23
Q

What are the branches of the inferior mesenteric artery?

A

L colic artery
Sigmoid arteries
Superior rectal artery

24
Q

What veins drain to the hepatic portal vein?

A

Gastric veins (R & L)
R gastro-omental vein
Superior pancreaticoduodenal vein
Splenic vein
Superior mesenteric vein

25
Q

What are the branches of the superior mesenteric vein?

A

Inferior pancreaticoduodenal vein
Jejunal and ileal veins
Ileocolic veins
Right colic vein
Middle colic vein

26
Q

What are the branches of the splenic vein?

A

L gastro-omental vein
Inferior mesenteric vein

27
Q

What are the branches of the inferior mesenteric vein?

A

Left colic vein
Sigmoid veins
Superior rectal vein

28
Q

What veins drain straight to the IVC?

A

Paraumbilical veins
Esophageal veins (via azygos)
Body wall veins
Middle and inferior rectal veins (drain to internal iliac)
Hepatic veins

29
Q

What kind of esophageal condition can occur due to liver cirrhosis?

A

Esophageal varices

30
Q

What condition is caused by excessive portal hypertension?

A

Varicose veins in the abdomen, such as the thoracoepigastric veins popping out and caput medusae (distended and engorged paraumbilical veins)

31
Q

Where does lymph from the foregut tend to drain to?

A

Celiac lymph nodes.

32
Q

Where can lymph from the liver drain to?

A

Diaphragmatic lymph nodes
Hepatic vein/IVC lymph nodes

33
Q

What is the lymph plexus of the liver called? Why is it significant?

A

Subcapsular lymph plexus.
Majority of intraperitoneal drugs are absorbed here.

Portal hypertension, cirrhosis, and HF causes this area to leak fluid into the abdomen, which is ascites.

34
Q

Where does the lymph from the body and tail of the pancreas drain to?

A

Lymph nodes along the splenic artery.

35
Q

Where does lymph from the head of the pancreas drain to?

A

Celiac and/or superior mesenteric lymph nodes.

36
Q

Where does lymph from the SI go to?

A

It goes to the various mesenteric lymph nodes, before congregating at the superior mesenteric lymph nodes.

37
Q

Where does lymph from the LI go to?

A

Paracolic nodes along the colon and mesenteric lymph nodes, which will all go to the inferior mesenteric lymph nodes.

38
Q

What is the general path of lymph from the abdominal viscera?

A

Hindgut organs go to inferior mesenteric.
Inferior mesenteric combines to superior mesenteric.
Midgut organs go to superior mesenteric.

Superior mesenteric goes to celiac nodes.
Foregut organs go to celiac nodes.

Celiac nodes go to the cisterna chyli.
Lumbar nodes go to the cisterna chyli.

Cisterna chyli goes to thoracic duct, which goes to L subclavian.

39
Q

What are the paired branches of the abdominal aorta?

A

Inferior phrenic arteries
Renal arteries
Lumbar segmental arteries
Gonadal arteries
Common iliac arteries

Special: Median sacral artery (unpaired)

40
Q

What is the branch of the inferior phrenic arteries?

A

Superior suprarenal arteries.

41
Q

What are the branches of the renal arteries?

A

Middle suprarenal artery
Inferior suprarenal artery
Ureteric artery

42
Q

What are the branches of the common iliac arteries?

A

Internal iliac arteries
External iliac arteries

43
Q

What are the veins that drain to the IVC directly?

A

Hepatic veins
Inferior phrenic veins
R suprarenal vein
R renal vein
L renal vein
R gonadal vein
Lumbar segmental veins
Median sacral vein
Common iliac veins
