The duodenum is an endocrine organ that produces hormones such as secretin, cholecystokinin (CCK), and enterogastrone to regulate digestion.

Bile salts are amphipathic molecules that emulsify large fat globules into smaller droplets, increasing the surface area for lipase enzymes to act upon.

Cholecystokinin (CCK) and secretin are produced by enteroendocrine cells located in the mucosa of the duodenum.

The stomach is divided into the cardia, fundus, body, and the distal pylorus, which connects to the duodenum.

Active absorption in the small intestine involves energy-dependent transport mechanisms for various nutrients, including glucose, amino acids, and sodium ions.

Secretin is produced by the S-cells in the mucosa of the small intestine, specifically the duodenum.

Both secretin and cholecystokinin are hormones secreted by the duodenal mucosa in response to chyme entering the small intestine.

The hepatopancreatic duct (formed by the common bile duct and pancreatic duct) opens into the duodenum at the major duodenal papilla.

Meckel's diverticulum is a common congenital anomaly resulting from the incomplete closure of the vitelline duct, occurring in the distal ileum.
