What is digestion in the stomach Duodenum Ileam Colon

Stomach: In the stomach, food is mixed with gastric juices, which contain hydrochloric acid and enzymes like pepsin. The acid kills bacteria and the pepsin begins the breakdown of proteins. The stomach churns the food into a semi-liquid mixture called chyme.

Duodenum: This is the first part of the small intestine. Here, chyme mixes with digestive juices from the pancreas and liver. Pancreatic juices contain enzymes that break down carbohydrates, proteins, and fats. Bile from the liver helps emulsify fats, making them easier to digest.

Ileum: This is the final section of the small intestine. Most of the absorption of nutrients (vitamins, minerals, carbohydrates, fats, proteins) into the bloodstream occurs here.

Colon: Also known as the large intestine, the colon absorbs water and electrolytes from the remaining indigestible food matter. It also forms and stores feces before defecation. Bacteria in the colon help break down some remaining material and produce certain vitamins.
