1
Q

Describe esophageus

A

Starts at C6 and enters abd at T10, Eso with stomach at T11. Arteries are from the celiac trunk and include L gastric and L Inf phrenic. Veins are L gastric (P) and eso azygos (S). Nerve supply is by Splanchnic and Vagus

A

Caput medusa, Sup and Inf epigastric (S) to round ligament (umbilical vein reinstated P) leads to wormlike abdomen

29
Q

What are the branches of SMA and what they supply

A

Inf panduod (distal duod and head panc), Mid colic (proximal T colon), right colic (A colon), Ileocecal (cecum and appendicular branch to appendix)

30
