Ans. The correct option is B.

A gland is a group of cells in an animal's body that produces substances for release into the bloodstream (endocrine gland) or into body cavities or its outward shell (exocrine gland).

There are two types of glands:

Endocrine glands secrete substances directly into the bloodstream.

Exocrine glands secrete substances into body cavities or their external surface.


The liver is large, reddish-brown organs that lie on the right side of the belly weight about 3 pounds.

It's the largest gland. The liver is an exocrine gland that secretes bile into the intestine is also an endocrine gland and a blood purifier.

The liver is a metabolic factory that synthesizes and breaks down a number of substances.


It's a pea-structured gland located at the base of the brain.

It's considered to be a master gland as it secretes multiple hormones to regulate the organs as easily as the different glands.

It secretes different hormones Growth hormone, Thyroid stimulating hormone, Adrenocorticotropic hormone (ACTH), Gonadotropic hormone, Follicle stimulating hormone, Luteinizing hormone, Prolactin, Melanocyte – stimulating hormone, Oxytocin, Vasopressin or antidiuretic hormone (ADH).


It's located in the neck, ventral to the larynx and the major hormones produced by this gland are triiodothyronine and thyroxine.

Thyroxine is a hormone that regulates the metabolism of carbohydrates, proteins and fats in the body.


It's located just below the stomach and is both exocrine and endocrine in function.

It secretes hormones similar as insulin, glucagon, somatostatin and pancreatic polypeptide.
