Digestive Process

An overview of the digestive process is as follows:

Ingestion → Mechanical Digestion (Chewing) → Chemical Digestion (Salivary Amylase) → Formation of Bolus → Swallowing → Peristalsis in oesophagus → Lower oesophageal Sphincter (LES) → Stomach → Pyloric Sphincter → Small Intestine( Duodenum, Jejunum, Ileum ) → Large Intestine (Colon) → Rectum → Anus

Gastrointestinal Tract – Diagram, Anatomy, & Disorders

The gastrointestinal (GI) tract is a long, twisting tube made up of hollow organs that starts at the mouth and ends at the anus. It comprises organs such as the mouth, esophagus, stomach, small intestine, and large intestine. Food taken in through the mouth undergoes the process of digestion in the stomach, absorption of nutrients and energy in the small intestine, and the waste stored in the large intestine is expelled at the anus as feces.

In this article, we will study in detail the definition of the gastrointestinal tract, its anatomy, digestive mechanism, functions of the GI tract, infection, and disorders that occur in the GI tract.

Conclusion: Gastrointestinal Tract

In conclusion, the gastrointestinal (GI) tract is a complex system important for digestion and nutrient absorption. It consists of organs such as the mouth, stomach, small intestine, and large intestine. The digestive system breaks down food into nutrients that can be absorbed into the blood. The body uses these nutrients for energy, growth, and repair. Diseases affecting the gastrointestinal tract can impact digestion, nutrient absorption, and overall health of the individual. Therefore, it is important to maintain the gastrointestinal health and take a balanced diet for the optimal functioning of the GI tract....
