GENERAL HISTOLOGY

Detailed explanation-1: -It is divided into three parts: the duodenum, jejunum and ileum. The beginning portion of the small intestine (the duodenum) begins at the exit of the stomach (pylorus) and curves around the pancreas to end in the region of the left upper part of the abdominal cavity where it joins the jejunum.

Detailed explanation-2: -The large intestine is the last part of the gastrointestinal (GI) tract, the long, tube-like pathway that food travels through your digestive system. It follows from the small intestine and ends at the anal canal, where food waste leaves your body.

Detailed explanation-3: -The duodenum is the shortest section, on average measuring from 20 cm to 25 cm in length. Its proximal end is connected to the antrum of the stomach, separated by the pylorus, and the distal end blends into the beginning of the jejunum.

Detailed explanation-4: -Duodenum. The duodenum is the first part of the small intestine that the stomach feeds into. Jejunum. The remaining small intestine lays in many coils inside the lower abdominal cavity. Ileum. The ileum is the last and longest section of the small intestine.
