Digestive System

In humans, digestion is a multi-stage process in the digestive system, starting from ingestion of raw materials. Digestion is separated into four steps:

  • Ingestion: placing food into the mouth (entry of food in the digestive system).
  • Mechanical and chemical breakdown: mastication and the mixing of the resulting bolus with water, acids, bile and enzymes in the stomach and intestine to break down complex molecules into simple structures.
  • Absorption: of nutrients from the digestive system to the circulatory and lymphatic capillaries through osmosis, active transport, and diffusion.
  • Egestion (Excretion): Removal of undigested materials from the digestive tract through defecation.

Diseases affecting the digestive system are addresed by a group of specialists comprising, Gastroenterologists, GI Surgeons, Vascular Surgeons, General Physicians, General Surgeons, Onco Surgeons, Medical Oncologists and Radiation Oncologists.
