    • Ileum is part of the small intestine which makes up 3/5 of its total length. Its main functions includes: (1)enzymatic cleavage of nutrients, (2)absorption of vitamin B12 (with intrinsic factor from the stomach), fats (especially fatty acids and glycerol) and bile salts, and (3)immunological function (access and transfer of antigens). Like the other parts of the GI tract, it has a basic pattern of 4 major layers namely: mucosa, submucosa, muscularis, and serosa. Peyer’s patches is the characteristic feature of ileum.

      Gall bladder is a small, pear-shaped organ which is located in the upper right portion of abdomen and sits under the liver. It is responsible in storing and releasing bile. Unlike the other structures of the digestive system, it has only 3 layers (mucosa , muscularis and serosa). The submucosa is absent in gall bladder.

      Esophagus is a fibromuscular tube which is approximately 25 cm long. It extends from the pharynx to the stomach. Anatomically, esophagus is divided into 3 parts (cervical, thoracic, and abdominal). Moreover, it has all the basic histological layers of the GI tract which are mucosa, submucosa, muscularis, and serosa. These layers aids the esophagus for the bulk movement of food from the mouth to the stomach.
