GENERAL HISTOLOGY

Detailed explanation-1: -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.

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: -The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum.

Detailed explanation-4: -The small intestine releases maltase, which is responsible for breaking down maltose (malt sugar) into glucose (simple sugar). The body uses glucose for energy. During digestion, starch is partially transformed into maltose by amylases. The maltase enzyme then changes maltose into glucose.

Detailed explanation-5: -The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum.
