Rotation brings ______ tail and ventral components of ______ together.
dorsal pancreas
52
Hepatic Diverticulum
know anatomy- listen to the lecture
The hepatic diverticulum (or liver bud) is a primordial cellular extension of the embryonic foregut endoderm that gives rise to the parenchyma of the liver.

59
STRUCTURES WITHIN THE PELVIS
| name
End of digestive system
Female reproductive organs
Bladder
Ducts to, and exiting from, bladder
60
pyloric sphincter
The pyloric sphincter is a thin, circular band of visceral muscle surrounding the pyloric opening at the inferior end of the stomach. It is found at the border of the stomach’s final segment, the pylorus, and the small intestine’s first segment, the duodenum..
61
The greater omentum
is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum which hangs down from the liver to the lesser curvature.
62
heaptic portal vein
is the system of veins comprising the hepatic portal vein and its tributaries. It is also called the portal venous system, although it is not the only example of a portal venous system, and splanchnic veins, which is not synonymous with hepatic portal system and is imprecise
63
bile duct
the duct that conveys bile from the liver and the gallbladder to the duodenum.
64
left colic flexture
The splenic (or left colic) flexure is a sharp bend between the transverse and the descending colon in the left upper quadrant of humans. The left colic flexure is near the spleen, and hence called the splenic flexure. There are two colic flexures in the transverse colon — the other being the hepatic flexure, as it is next to the liver, in the right upper quadrant.
65
more info about stuff
The ventral mesentery forms the lesser omentum, and is attached to the developing liver. In the adult, these connective structures of omentum and mesentery form the peritoneum, and act as an insulating and protective layer while also supplying organs with blood and lymph vessels as well as nerves.
66
liver
develops in ventral mesentary,filter all of the blood you absorb goes to liver first, endodermal cells will make the liver growing of liver splits mesentary
67
faliciform ligament
part of ventral mesentary, above liver, attached to body wall, still attaches to part of old ventral margin of liver and body wall has been streatched to right
68
less omentun
part of gut and liver called lesser omentum
69
mesentarys never
deaatch from their original connections
70
lesser omentrum
runs between liver and gut tube, never change attachments ever ever changes from vertical to horizontal never deattaches
71
greater omentum
overgrows, no longer suspends guts The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach. overstretches into a big floppy bag- primary reason: attached to guts/stomach mostly, put lots of bad stuff full of immune system components lots of lymphatic tissue
72
epiolic foramen
The epiploic foramen (also called the foramen of Winslow) is a passage between the greater (general peritoneal space) and lesser sac (omental bursa) allowing communication between these two spaces.
73
stomach between liver
lesser omen
74
midgut
in the region of the midgut because of the umbelical hernia the ventral mesentary is lost
75

abdominal cavity
Retroperitoneal
