Detailed explanation-1: -The small intestine is divided into the duodenum, jejunum, and ileum. The small intestine follows the general structure of the digestive tract in that the wall has a mucosa with simple columnar epithelium, submucosa, smooth muscle with inner circular and outer longitudinal layers, and serosa.

Detailed explanation-2: -The large intestine has four parts: cecum, colon, rectum, and anal canal. Partly digested food moves through the cecum into the colon, where water and some nutrients and electrolytes are removed.

Detailed explanation-3: -Main parts of the large intestine are cecum, colon, rectum and anus. The small intestine consists of three parts. The first part, called the duodenum, connects to the stomach. The middle part is the jejunum.

Detailed explanation-4: -Duodenum can be divided into four parts: the first (superior), the second (descending), the third (horizontal) and the fourth (ascending) parts.
