Mouth
Mouth

The oval-shaped oral cavity located at the apex of the digestive tract and consisting of two parts

Esophageal Sphincter, Upper
Esophageal Sphincter, Upper

The structure at the pharyngoesophageal junction consisting chiefly of the cricopharyngeus muscle. It normally occludes the lumen of the ESOPHAGUS, except during SWALLOWING.

Esophageal Sphincter, Lower
Esophageal Sphincter, Lower

The physiologic or functional barrier to GASTROESOPHAGEAL REFLUX at the esophagogastric junction. Sphincteric muscles remain tonically contracted during the resting state and form the high-pressure zone separating the lumen of the ESOPHAGUS from that of the STOMACH. (Haubrich et al, Bockus Gastroenterology, 5th ed., pp399, 415)

Ampulla of Vater
Ampulla of Vater

A dilation of the duodenal papilla that is the opening of the juncture of the COMMON BILE DUCT and the MAIN PANCREATIC DUCT, also known as the hepatopancreatic ampulla.

Sphincter of Oddi
Sphincter of Oddi

The sphincter of the hepatopancreatic ampulla within the duodenal papilla. The COMMON BILE DUCT and main pancreatic duct pass through this sphincter.

Intestines
Intestines

The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE.

Intestinal Mucosa
Intestinal Mucosa

Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

Paneth Cells
Paneth Cells

Differentiated epithelial cells of the INTESTINAL MUCOSA, found in the basal part of the intestinal crypts of Lieberkuhn. Paneth cells secrete GROWTH FACTORS, digestive enzymes such as LYSOZYME and antimicrobial peptides such as cryptdins (ALPHA-DEFENSINS) into the crypt lumen.

Goblet Cells
Goblet Cells

A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.

Enterocytes
Enterocytes

Absorptive cells in the lining of the INTESTINAL MUCOSA. They are differentiated EPITHELIAL CELLS with apical MICROVILLI facing the intestinal lumen. Enterocytes are more abundant in the SMALL INTESTINE than in the LARGE INTESTINE. Their microvilli greatly increase the luminal surface area of the cell by 14- to 40 fold.

Intestine, Large
Intestine, Large

A segment of the LOWER GASTROINTESTINAL TRACT that includes the CECUM; the COLON; and the RECTUM.

Anal Canal
Anal Canal

The terminal segment of the LARGE INTESTINE, beginning from the ampulla of the RECTUM and ending at the anus.

Cecum
Cecum

The blind sac or outpouching area of the LARGE INTESTINE that is below the entrance of the SMALL INTESTINE. It has a worm-like extension, the vermiform APPENDIX.

Appendix
Appendix

A worm-like blind tube extension from the CECUM.

Colon
Colon

The segment of LARGE INTESTINE between the CECUM and the RECTUM. It includes the ASCENDING COLON; the TRANSVERSE COLON; the DESCENDING COLON; and the SIGMOID COLON.

Colon, Sigmoid
Colon, Sigmoid

A segment of the COLON between the RECTUM and the descending colon.

Colon, Ascending
Colon, Ascending

The segment of LARGE INTESTINE between the CECUM and the TRANSVERSE COLON. It passes cephalad from the cecum to the caudal surface of the right lobe of the LIVER where it bends sharply to the left, forming the right colic flexure.

Colon, Descending
Colon, Descending

The segment of LARGE INTESTINE between TRANSVERSE COLON and the SIGMOID COLON.

Colon, Transverse
Colon, Transverse

The segment of LARGE INTESTINE between ASCENDING COLON and DESCENDING COLON. It passes from the RIGHT COLIC FLEXURE across the ABDOMEN, then turns sharply at the left colonic flexure into the descending colon.

Rectum
Rectum

The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.
