GENERAL HISTOLOGY

Detailed explanation-1: -Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder. The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile.

Detailed explanation-2: -The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion.

Detailed explanation-3: -The absorptive surface area of the small intestine is increased by plicae circulares, villi, and microvilli.

Detailed explanation-4: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins.

Detailed explanation-5: -The pancreas produces digestive enzymes that help break down proteins, carbohydrates and fats. Liver. The liver produces bile, a solution that helps you digest fats. Gallbladder.
