stomach/intestinese

4 major functions of the stomach

1. storage of food

2. mechanical breakdown of food

3. dissolution of chemical bonds via acids and enzymes

4. production of intrinsic factor

Located posterior to the stomach are the x

spleen, the left adrenal gland and kidney and the body and tail of the pancreas

rugae

folds in the inner stomach

how long is the small intestine

6-7m

The proximal portion of the small intestine is the

duodenum

The duodenum is mostly x, making it less mobile than the rest of the small intestine

retroperitoneal

first 2 inches of the duodenum, the conical-shaped

duodenal bulb

duodenum suspended in the abdomen by the

hepatoduodenal ligament

most common site for peptic ulcer formation

hepatoduodenal ligament

what portion of the duodenum contains the ampulla of vater?

second descending portion

The duodenojejunal flexure is fixed in place by the

ligament of Treitz

The x is the longest portion of the small intestine

ileum

The jejunum is approximately 2.5 m long (about 40% of the small bowel) and occupies the x

left upper abdomen or umbilical region of the abdomen

bulk of chemical digestion and nutrient absorption occurs

jejunum

It is in the ileum that x from the stomach combines with vitamin B12 for absorption in the terminal ileum

intrinsic factor

Vitamin B12 is essential for x

normal red blood cell formation and nervous system function.

The loops of ileum terminate at the x

ileocecal valve

The outer, longitudinal muscle of the large intestine forms three thickened bands called

taeniae coli

haustra

pouchlike folds in the large intestine

On the outer surface of the large intestine are small fat-filled sacs of omentum called the x

epiploic appendages

The colon is the longest portion of the large intestine and can be subdivided into four distinct portions:

ascending, transverse, descending, and sigmoid

The x marks the beginning of the transverse colon

hepatic flexure

x and the beginning of the descending colon

splenic flexure

The major functions of the large intestine include x

reabsorption of water and the storage and elimination of fecal material
