Question

Enterogastrone is secreted by
A. Gastric mucosa
B. Esophageal mucosa
C. Saliva
D. Duodenal mucosa

Answer 1

A hormone is a type of molecule that belongs to a member of a class of signalling molecules. The hormones are transported by the circulatory system to target organs to regulate physiology and behaviour. They are produced by several glands in multicellular organisms. Enterogastrone is a type of hormone. The hormones form a part of the signalling system of the body.

Complete step by step answer: The hormone is a regulatory substance found in an organism. Hormone is transported in tissue to operate specific cells or tissues into action where it is present in the form of fluids such as blood or sap. Hormones are known as chemical messengers of the body. They travel in the bloodstream to reach the target tissues or organs and are very specific in action. The work of hormones going slowly, over time, and it affects many different processes such as growth and development of the human body, regulates the process of metabolism through which the body gets energy from the foods. Hormones are also effective in sexual function and reproduction. Hormones can be exocrine or endocrine in secretion.
Enterogastrone hormone secreted by the duodenal mucosa present in the small intestine. It is secreted when fatty food is present in the stomach or small intestine. It is also said that this hormone releases when sugars and proteins are in the intestine. Enterogastrone is circulated by the bloodstream to the glands and muscles of the stomach. This enterogastrone is responsible for the inhibition of gastric movements and secretions, through the blocking the production or activity of gastrin.
The gastric mucosa is the mucous membrane layer of the stomach. The mucosal layer of the stomach contains the glands and the gastric pits. It is responsible for the releases of pepsinogen and hydrochloric acid.
The oesophageal mucosa is a tabular squamous epithelium of around three layers of squamous cells. It helps in the digestive system and prevents the gastric acid of the stomach.
Saliva is a water like fluid secreted into the mouth by glands. It provides lubrication for chewing and swallowing, and aids in digestion.
Therefore, the correct option is option D.

Note: The hormone is a protein-enriched substance present in living organisms. It acts as a chemical messenger. It is transported to different organs through a circulatory system for the purpose of various functions such as regulating human growth and development, sexual function, reproduction, etc. Enterogastrone is a hormone secreted by the duodenal mucosa and regulates the function of gastric acid.
