Question

Heterocrine glands are the glands, which

A.Work as exocrine glands.
B.Work as endocrine glands.
C.Have dual (Exo and endocrine)mode of function
D.None of the above

Answer 1

Hint A gland is a group of cells that synthesizes substances like hormones, enzymes, etc. Hormones and enzymes play a vital role in the growth, development, and metabolism process in our body.

Complete Step-by-step answer:
Endocrine glands release substances directly into the bloodstream while exocrine glands release the substance into a duct or opening inside or outside the body.
The heterocrine gland has a dual mode of function i.e., they work as an endocrine as well as an exocrine gland. The pancreas is an example of heterocrine glands.
The pancreas is located in the abdomen. It is a part of the digestive system and plays a crucial role in the digestion of food. Apart from these, it regulates blood sugar The pancreas as an endocrine gland secretes hormones like insulin and glucagon directly into the bloodstream. As an exocrine gland, the pancreas secretes enzymes through the pancreatic duct into the duodenum.
Apart from the pancreas ovary and testes are examples of heterocrine glands. The ovary releases steroid hormones ( estrogen and progesterone) into the bloodstream and also performs exocrine functions by producing ova into the duct.
Hence the correct answer is option C.
Note: The endocrine gland are ductless glands; the secretory product is mainly a hormone that is directly released into the bloodstream. While exocrine glands have ducts and the secretory product is sweat, enzymes, mucus, etc that are released into the external surface or internal organ through ducts.
