HUMAN NUTRITION

Detailed explanation-1: -Digestion ends in the small intestine of the human body. The digestive process starts in the mouth and finishes in the small intestine. The small intestine, which has three parts called the duodenum, jejunum, and ileum, uses bile from the liver and enzymes secreted by the pancreas to break down food.

Detailed explanation-2: -The small intestine extends from the pyloric sphincter to the ileocecal valve, where it empties into the large intestine. The small intestine finishes the process of digestion, absorbs the nutrients, and passes the residue on to the large intestine.

Detailed explanation-3: -Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

Detailed explanation-4: -Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates.

Detailed explanation-5: -The small intestine is where most of the long process of digestion takes place. It: Systematically breaks food down. Absorbs nutrients.
