Question

Answer

Glands are the organs of the human body which manufacture some liquid products which are secreted internally or externally from the cells. Mainly there are two types of glands namely ducted glands and ductless glands. Ducted glands secrete their products through well defined ducts like liver, salivary, sweat glands etc. Whereas Ductless glands which are also known as internally secreting glands or endocrine glands secrete their products or hormones directly into the blood stream in response to instructions from the brain. The blood then carries them around the body where they control internal chemical processes. Hence they are linked with the nervous system and also with the circulatory system and their secretions are known as hormones or enzymes. This article deals with the ductless glands, where they are located in the body, secretion and function.

Answer

Introduction:
In the human body, there are two types of glands: ductless glands and duct glands. Ductless glands, also known as endocrine glands, release their secretions (hormones) directly into the bloodstream, while duct glands release their secretions through ducts or tubes. The question asks for the gland that is not a ductless gland.

Explanation:
Let's analyze each option to determine which one is not a ductless gland:

a) Adrenal:
The adrenal glands are located on top of the kidneys and are ductless glands. They produce hormones such as adrenaline, cortisol, and aldosterone, which are released directly into the bloodstream.

b) Liver:
The liver is not a gland. It is an essential organ involved in various metabolic processes, including detoxification, protein synthesis, and production of bile. The liver does not produce hormones, so it does not fit the criteria of being a gland.

c) Thyroid:
The thyroid gland is a ductless gland located in the neck. It produces hormones such as thyroxine (T4) and triiodothyronine (T3), which regulate metabolism and growth. These hormones are released directly into the bloodstream.

d) Pituitary:
The pituitary gland is often referred to as the 'master gland' because it controls the functions of several other endocrine glands. It is a small, pea-sized gland located at the base of the brain. The pituitary gland produces and releases various hormones that regulate growth, reproduction, and the function of other glands. These hormones are secreted directly into the bloodstream.

Conclusion:
Based on the analysis, the gland that is not a ductless gland is the Liver. It is an organ involved in various metabolic processes, but it does not produce hormones and therefore does not meet the criteria of being a gland.
