Detailed explanation-1: -The small intestine is responsible for absorption of nutrients, salt, and water. On average, approximately nine liters of fluid enters the jejunum each day. The small intestine absorbs approximately seven liters, leaving only 1.5-2 liters to enter the large intestine.

Detailed explanation-2: -It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.

Detailed explanation-3: -Absorption of nutrients from food is the primary function of the small intestine. The food is converted into much smaller particles so that it mixes with the blood and can be carried throughout the body.

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 muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.
