Question

Secretin hormone is secreted by and stimulates

Answer 1

Hint: Hormones are the chemical messengers that are directly secreted in the blood by the endocrine glands (ductless glands). Blood carries these hormones to the particular organ or tissue of the body to exert their functions.

Complete step by step answer:
Secretin hormone is the digestive hormone which regulates the water homeostasis throughout the body. It is the peptide hormone which consists of 27 amino acids. The hormone secretion was discovered by the British physiologist Sir William M. Bayliss and Ernest H. Starling in 1902. It is secreted by the S cells of the duodenum (part of the intestine). In humans, secrein protein is encoded by the SCT gene. Secretin hormone stimulates the Pancreas. The precursor of hormone secretion is the prosecution. Secretin is stored in the inactive form and get activated by the action of gastric ACIDS.
Functions of hormone secretin:
1.Secretin helps in regulating the pH of the duodenum by
2.Inhibiting the secretion of gastric acid from the parietal cells of the stomach.
3.Stimulating production of bicarbonate from the ductal cells of the pancreas.
4.Therefore, it has been clear from the above discussion that the secrein hormone is secreted by the S cells of the duodenum and it stimulates the pancreas.

Note: Secretin hormone is used in the diagnostic tests for the pancreatic function. Secretin is injected into the person and the pancreatic output can then be imaged with the help of magnetic resonance imaging technique. Secretin hormone can also be produced with the help of recombinant DNA technology. It was first produced with the help of recombinant DNA technology in 2004.
