The process of digestion is facilitated by special chemicals called digestive
enzymes. Most digestion and absorption take place in the small intestines.
11.
In order after the stomach, the three areas of the small intestines are the
duodenum, the jejunum, and the ileum. The jejunum and the ileum are attached to
the rear wall of the abdomen with a membrane called the mesentery. (para 6-9a)
12.
Folds on the inner surfaces of the small intestines are known as plicae.
Finger-like projections from these folds are known as villi. (para 6-9c)
13.
The digestive function of the liver is to produce a fluid called bile (gall). The
common bile duct joins with the duct of the pancreas as the fluid enters the
14.
The texture of the pancreas is soft and pliable. Pertaining to location, the
pancreas is stretched across the posterior wall of the abdomen. (para 6-11)
15.
The primary function of the large intestine is to salvage water and electrolytes.
The large intestines remove water until a nearly solid mass is formed before
16.
In order, the major subdivisions of the large intestines are the cecum, the
ascending colon, the transverse colon, the descending colon, and the sigmoid
17.
The rectum terminates in the narrow anal canal, at the end of which is an opening
called the anus. Muscles called anal sphincters aid in the retention of feces until

Attached to the cecum is a mass of lymphoid tissue called the vermiform
