The site of production of cholecystokinin is:
a. The stomach
b. The small intestine
c. The pancreas
d. The large intestine

검증된 단계별 안내

Understand that cholecystokinin (CCK) is a hormone involved in digestion, particularly in stimulating the release of digestive enzymes and bile.

Recall that hormones like CCK are produced by specific cells located in certain parts of the digestive system.

Identify the main regions of the digestive tract: stomach, small intestine, pancreas, and large intestine.

Know that CCK is secreted by the I-cells, which are specialized cells found in the mucosal lining of the small intestine, especially in the duodenum and jejunum.

Conclude that the correct site of production of cholecystokinin is the small intestine.

Cholecystokinin (CCK)

Cholecystokinin is a digestive hormone that stimulates the digestion of fats and proteins. It triggers the release of digestive enzymes from the pancreas and bile from the gallbladder, aiding in nutrient breakdown and absorption.

Site of Hormone Production in the Digestive System

Different hormones are produced in specific parts of the digestive tract. Understanding where hormones like CCK are secreted helps identify their role in digestion and their target organs.

Role of the Small Intestine in Digestion

The small intestine is a key site for nutrient absorption and hormone secretion. It produces hormones like CCK in response to food entering from the stomach, coordinating digestive processes.
