Name the hormone secreted by the pancreas. What is the function of this hormone ?

 

Best Answer

Explanation:

Pancreas is a composite gland meaning it acts as both endocrine and exocrine gland.

The endocrine part of the pancreas consists of Islets of Langerhans that represent 1-2% of pancreatic tissue.

There are mainly two types of cells in Islets of Langerhans-  and  cells.

The - cells secrete glucagon hormone and - cells secrete insulin hormone.

Glucagon and insulin are peptide hormones that together maintain normal blood glucose levels.

Glucagon acts on liver cells and stimulates glycogenolysis(breakdown of glycogen) and it also forms new glucose(gluconeogenesis). 

It also reduces the uptake of glucose by cells i.e. increases the glucose levels in the blood and so it is called hyperglycemic hormone.

Whereas insulin works just opposite to glucagon.

It acts on liver cells and cells of adipose tissue and increases the uptake of glucose.

It acts to convert glucose to glycogen(glycogenesis)

Hence it is called hypoglycemic hormone.

Final Answer:

Hormone secreted by the pancreas is glucagon and insulin and they regulate the blood glucose levels.
