GASTROINTESTINAL OR DIGESTIVE TRACT
The gastrointestinal tract, also called the digestive tract, or alimentary canal, is the system of organs that allow us to consume food and digest it to extract energy and nutrients and expel the remaining waste. The main functions of the gastrointestinal tract are ingestion, digestion, absorption and excretion.
In a normal adult man, the gastrointestinal tract is approximately 6.5 m long, divided into the upper gastrointestinal tract and the lower intestinal tract.
UPPER GASTROINTESTINAL TRACT
The upper gastrointestinal tract begins in the mouth, continues in the pharynx then the esophagus and stomach. The mouth contains the oral mucosa and the mouths of the salivary glands, tongue and teeth. Behind the mouth is the pharynx, which leads to an empty muscular tube that is the esophagus.
Peristalsis begins, which is the contraction of the muscles to propel food down the esophagus that extends through the chest and crosses the diaphragm to reach the stomach. The stomach leads to the small intestine.
LOWER INTESTINAL TRACT
The lower intestinal tract is composed of the intestine and the anus. Small intestine has three parts:
Blind (the vermiform appendix is attached to the blind)
Colon (ascending colon, transverse colon, descending colon and sigmoid colon)
The accessory organs of the alimentary canal include, to the liver the gallbladder and the pancreas.
The liver secretes bile in the small intestine via the biliary system, using the gallbladder as a reservoir. In addition to storing and concentrating bile, the gallbladder has no other specific function. The pancreas secretes an isosmotic fluid that contains bicarbonate and various enzymes, including trypsin, chymotrypsin, lipase and pancreatic amylase, as well as nucleolytic enzymes (deoxyribonuclease and ribonuclease) within the small intestine. These two secretory organs help digestion.
Among the most common diseases of the digestive system can be found:
- Gastroesophageal Reflux Disease
- Celiac disease or celiac disease
- Crohn's disease
- Ulcerative colitis
- Irritable bowel syndrome
