Question

What is succus entericus?

Answer 1

An intestinal gland is a gland situated between villi in the small and large intestine epithelial lining (or colon). The glands and intestinal villi are covered by epithelium, a layer of cells that includes enterocytes (cells that absorb water and electrolytes), goblet cells (cells that secrete mucus), enteroendocrine cells (cells that secrete hormones), cup cells, tuft cells, and other cells, Paneth cells (which secrete antimicrobial peptides) and stem cells are found at the gland's base.
Intestinal glands can be found in the epithelia of the small intestine, such as the duodenum, jejunum, and ileum, as well as the epithelia of the large intestine, where they're known as colonic crypts.

Complete answer:
Succus entericus, commonly known as intestinal juice, is a little amount of fluid secreted in the small intestine. Succus entericus is an alkaline secretion made up of water, mucoproteins, and carbonate hydrogen ions produced by glands in the duodenal wall. The secretions of the mucosal brush border cells and the secretions of goblet cells combine to generate this intestinal juice. It protects the duodenum from harm by helping to offset the highly acidic and proteolytic chyme that enters the small intestine from the stomach.
The clear to pale yellow fluid secretions from the glands lining the small intestine walls are referred to as intestinal juice (also known as succus entericus). Hormones, digestive enzymes, mucus, and chemicals to counteract hydrochloric acid from the stomach are all found in intestinal juice.
It secretes mucus and contains enzymes such as lipase, lactase, enterokinase, and amylase.

Note:
Digestive enzymes are stored in the enterocytes of the small intestinal mucosa and are used to break down certain meals as they pass through the epithelium. Peptidase, sucrase, maltase, lactase, and intestinal lipase are among these enzymes. In contrast, pepsinogen is secreted by main cells in the stomach's gastric glands.
New epithelium is also generated here, which is necessary because the cells at this place are constantly worn away by passing food. Multipotent stem cells are found in the crypt's basal (far from the intestinal lumen) part. One of the two daughter cells remains in the crypt as a stem cell during each mitosis division, while the other develops and migrates up the crypt's side, eventually into the villus. The cells produced in this way include goblet cells. The differentiation of intestinal stem cells has been linked to a number of genes.
