Tongue
The tongue is a moveable muscular process in the mouth that manipulates food for mastication and is used in the act of swallowing. The tongue’s upper surface is covered by taste buds housed in numerous papillae.
Esophagus
The esophagus is a muscular tube through which food passes from the mouth (pharynx) to the stomach. The muscular layer of the esophagus wall is composed of skeletal muscle in the upper part, smooth muscle in the lower part, and a mixture of the two in the middle.
Stomach
The stomach digests food by acidification and the breakdown of proteins. It is divided into three histological regions (cardiac, body/fundus and pyloric) based on their anatomical location and appearance of their glands.
Vasculature of the Gastric Mucosa
The blood supply to the stomach wall can be seen after perfusion with a colored dye.
Small Intestine
The small intestine is involved in the continued digestion of food and the absorption of nutrients. It is divided into three segments: duodenum, jejunum, and ileum.
