Histology Art (MT 30 – J) 3 years, 8 months ago The digestive system takes in food, digests and absorbs nutrients, and excretes waste. The mouth cavity, esophagus, stomach, small intestine, and large intestine, as well as accompanying digestive organs such as the salivary glands, pancreas, liver, and gallbladder, make up the digestive system.Food goes from the mouth or pharynx to the stomach via the esophagus, which is a muscular tube. The esophageal wall’s muscular layer is made up of skeletal muscle in the upper section, smooth muscle in the lower part, and a combination of the two in the center.
Acidification and protein breakdown is used to digest food in the stomach. Because of its anatomical position and the appearance of its glands, it is separated into three histological regions: cardiac, body or fundus, and pyloric.
Water is absorbed by the large intestine, while waste material is consolidated into feces. The cecum, appendix, colon, rectum, and anal canal are the sections that make up the intestine.

There are three sections to the small intestine:
The duodenum is the stomach’s proximal section. Villi are long, narrow projections that protrude into the lumen. Brunner’s Glands are the sole submucosal glands in the gastrointestinal tract (together with the esophagus).
The jejunum is the middle section of the intestine. Villi are long, narrow projections that protrude into the lumen. There are no submucosal glands.
Ileum is the distal section of the large intestine. Villi are short, wide finger-like projections that protrude into the lumen and have blunt tips. There are no submucosal glands. Peyer’s Patches are lymphoid cell aggregations in the lamina propria.
