Question

Hormone which control the secretion of intestinal juice is
A.Enterogastrone
B.Enterocrinin
C.Duocrinin
D.Both B and C.

Answer 1

Hint: Many hormones are required for proper digestion of food. Intestinal juice has hormones that help the food to get digested when the food is in the intestine.

Complete answer:
The digestion of food already begins from the mouth itself and when the food reaches the stomach, gastrin which itself is a hormone released by the pyloric part of the stomach stimulates different gastric glands to release hormones that are required for digestion.
When the food reaches the duodenum of the intestine, the hormone known as enterogastrone is released by the duodenum which inhibits the further secretion of gastric acid and regulates the secretions of the intestinal juice.

Option A: Enterogastrone is the hormone that controls the secretion of intestinal juices. Therefore, this is the correct option.

Option B: Duocrinin is also secreted by the duodenum but it is responsible for the secretion of mucus from the Brunner's gland to the intestinal juice. Therefore, this is the incorrect option.

Option C: The Enterocrinin hormone released by the small intestine releases enzymes from the crypts of lieberkuhn into the intestinal juice. Therefore, this is the incorrect option.

Option D: Both options B and C are incorrect. Therefore, this is the incorrect option.

Hence, the correct answer is option (A)

Note: The intestinal juice which is also known as the succus entericus is a yellow fluid like secretion that consists of many enzymes such as lipase, amylase, enterokinase, lactase, erepsin, nucleases, nucleosidases, etc and it also contains mucus membranes that border the intestine. The succus entericus helps in the hydrolysis of the food and digestion of carbohydrates, lipids, etc coming to the small intestine. The ph of this intestinal juice is 7.8, which means it is slightly alkaline.
