NEET PG DENTAL EXAM

Detailed explanation-1: -Duodenum: This short section is the part of the small intestine that takes in semi-digested food from your stomach through the pylorus, and continues the digestion process. The duodenum also uses bile from your gallbladder, liver, and pancreas to help digest food.

Detailed explanation-2: -The pylorus is the part of the stomach that connects to the small intestine. It includes the pyloric sphincter, which is a thick ring of muscle that acts as a valve to control the emptying of stomach contents (chyme) into the duodenum (first part of the small intestine).

Detailed explanation-3: -The three regions of the small intestine are the duodenum, jejunum, and ileum. The jejunum is about 0.9 meters (3 feet) long (in life) and runs from the duodenum to the ileum. Jejunum means “empty” in Latin and supposedly was so named by the ancient Greeks who noticed it was always empty at death.

Detailed explanation-4: -Abstract. Gastric emptying is the process by which the contents of the stomach are moved into the duodenum. This is accomplished by three mechanisms: (1) Peristaltic waves, (2) systolic contractions of the antrum, and (3) reduction in size of the stomach.
