The small intestine is an important part of the digestive system, responsible for absorbing nutrients from the food we eat. It is a long tube, measuring around 6 meters in length, and is located between the stomach and the large intestine. The small intestine is divided into three parts: the duodenum, the jejunum, and the ileum.

Enzymes and their Role

Enzymes are proteins that act as catalysts for chemical reactions in the body. They play an important role in the digestive process by breaking down large molecules, such as carbohydrates, proteins, and fats, into smaller molecules that can be absorbed by the small intestine. Some enzymes are produced by the pancreas and released into the small intestine, while others are produced by the small intestine itself.

One important enzyme produced by the small intestine is lactase, which is responsible for breaking down lactose, a sugar found in milk and dairy products. Without lactase, lactose would pass through the digestive system without being fully digested, causing bloating, gas, and diarrhea in people who are lactose intolerant.
