Define mesentry
A fold in the peritoneum which connects an organ to the posterior wall of the abdomen
Define retroperitoneum?
The space between the peritoneum and the posterior abdominal wall that contains especially the kidneys and associated structures, the pancreas, and part of the aorta and inferior vena cava.
What is an omentum?
A fold of peritoneum connecting the stomach with other abdominal organs.
What are the two omenta and what do they connect?
The greater omentum is a prominent peritoneal fold that hangs down from the greater curvature of the stomach anterior to the transverse colon, to which it is attached.
The lesser omentum attaches the lesser curvature of the stomach to the liver superiorly.
What travels between folds of the peritoneum?
Arteries, therefore, and arterial branch supplying an organ with a mesentery, will travel between the folds of that mesentery.
Is the peritoneal sac closed in men and women?
