The Gastrointestinal Tract is a complex system responsible for the digestion and absorption of food. It begins at the mouth, where food is ingested, and continues through the esophagus, stomach, small intestine, and large intestine, ultimately leading to the rectum. Each part plays a crucial role in breaking down food and extracting nutrients. In addition to digestion, the gastrointestinal tract also helps in the elimination of waste. It is lined with a mucous membrane that protects the organs and facilitates the movement of food. Proper functioning of this system is essential for overall health and well-being.
