PATHOLOGY

Detailed explanation-1: -The primary function of the jejunum is to absorb sugars, amino acids, and fatty acids. Both the jejunum and ileum are peritoneal. The ileum absorbs any remaining nutrients that did not get absorbed by the duodenum or jejunum, in particular vitamin B12, as well as bile acids that will go on to be recycled.

Detailed explanation-2: -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-3: -The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
