Question

Succus entericus is the name given to-
A. A junction between the ileum and large intestine
B. Intestinal juice
C. Swelling in the gut
D. Appendix

Answer 1

Hint: Succus entericus is the alkaline secretion produced by glands in the walls of the duodenum. It consists of water, mucoproteins and hydrogen carbonate ions.

Complete Answer:
Succus entericus is also known as intestinal juice and it is pale yellow in colour. It protects the duodenum from damage by counteracting the highly acidic and proteolytic chyme entering the small intestine from the stomach.
- Option A: The junction between the ileum and large intestine is called the Cecum or Caecum. It is a pouch within a peritoneum that receives chyme from the ileum and is considered to be the beginning or the connection to the ascending colon of the large intestine. Thus, this is an incorrect option.
- Option B: Succus entericus is the fluid secreted in the intestines in small quantities and contains enzymes like disaccharidases (e.g. maltase), dipeptidases, lipases, nucleosidases, etc. for the digestion of carbohydrates, proteins, fats, nucleic acids, etc. Therefore it is also called as Intestinal Juice and hence this is the correct option.
- Option C: The group of diseases or disorders that causes the swelling and inflammation of the gut are called Inflammatory Bowel Diseases (IBD), e.g, Crohn’s Disease, which occurs when there is redness, swelling, and sores along the digestive tract. Thus, this is an incorrect option.
- Option D: Appendix also called the Vermiform appendix or Cecal appendix or Vermix or Vermiform process is a muscular structure attached to the large intestine in the human body. Thus, this is an incorrect option.

Thus, the correct option is B) Intestinal Juice.

Note: Intestinal Juice or succus entericus releases gastrointestinal hormones into the bloodstream, contains digestive enzymes that facilitate the digestion and absorption of food, and neutralizes hydrochloric acid coming from the stomach.
