GENERAL HISTOLOGY

Detailed explanation-1: -Your pancreas creates natural juices called pancreatic enzymes to break down foods. These juices travel through your pancreas via ducts. They empty into the upper part of your small intestine called the duodenum. Each day, your pancreas makes about 8 ounces of digestive juice filled with enzymes.

Detailed explanation-2: -Secretin, a peptide hormone comprising 27 amino acids, is secreted by the entero-endocrine S-cells of the duodenum and jejunum. It stimulates the production and release of bicarbonate ions by the pancreas; these accumulate in the pancreatic juice, giving it an alkaline pH of around 8-8.6.

Detailed explanation-3: -These acinar cells secrete enzyme-rich pancreatic juice into tiny merging ducts that form two dominant ducts. The larger duct fuses with the common bile duct (carrying bile from the liver and gallbladder) just before entering the duodenum via a common opening (the hepatopancreatic ampulla).

Detailed explanation-4: -After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas. The absorption of vitamins, minerals, and other nutrients begins in the duodenum.

Detailed explanation-5: -Secretes bicarbonate ions into the duodenum to neutralise stomach acids (intestine pH is usually   7 – 8) Also secretes lipase (for fat digestion), amylase (for carbohydrate digestion) and protease (for protein digestion) More items
