GAS1 Lab 5 - Abdominal Cavity In Situ

OBJECTIVES:

GAS1.5.1 Identify parietal and visceral peritoneum and their major reflections.

GAS1.5.2 Identify the boundaries of the lesser omental sac, its communication (omental foramen) with the greater omental sac and organs that are anterior, posterior, superior, and inferior.

GAS1.5.3 Indicate which of the abdominal organs are inter-peritoneal or retro-peritoneal. Identify the surface projections of each of the organs.

GAS1.5.4 Identify the parts and peritoneal coverings of the organs.

Begin with the abdominal cavity.

	What is the function of the parietal peritoneum?
It covers the retro-peritoneal organs.

Add in major organs of the retroperitoneum:

	Add the kidneys.
	Add the pancreas.

Note that the tail of the pancreas is considered interperitoneal. (See drawing)

Add the duodenum.
