Q

What is mesentery?

A

A fused double layer of peritoneum that encolses the intestine. It attaches the intraperitoneal structures in the abdominal cavity to the abdominal wall (suspends organs in A cavity. Is a conduit for blood vessels, lympathic vessels, and nerves. Holds the organs, lets it go where it wants but has restrictions. “Leash”

Q

Differences between P

A

Peritoneum-thin, single, continuous serous (2 layers-pareital and visceral) membrane. Covers most of the abdominal viscera.
Mesentery- double layer of serous membrane. 2 membranes fused
together.Holds & suspends the intestines from AW.
Omenta-double layer of peritoneum that connects to stomach to other viscera.

A

Peritoneal ligament

22
