Question

Endocrine glands produce or action of endocrine gland is mediated through
A. Hormones
B. Enzymes
C. Minerals
D. Vitamins

Answer 1

Hint: Endocrine glands produce chemical substances that act as messengers in our body and their role in human body physiology helps us in understanding their nature.

Complete Step by Step Answer:
Endocrine glands are part of the endocrine system which acts as a messenger system. They release chemical messengers, also known as hormones, directly into the bloodstream as they lack ducts (ductless). These hormones regulate distant target organs and are transported via the bloodstream to various organs and tissues throughout the body where they help in maintaining homeostasis.
The formation of glands occurs by an ingrowth from an epithelial surface. The glands secrete the hormones into the bloodstream via the basal lamina. The basal lamina is a layer around the glands to which many tiny blood vessels are attached.
The nine major glands of the endocrine system-
- Pineal gland
- Pituitary gland
- Thyroid gland
- Parathyroid gland
- Hypothalamus
- Adrenal gland
- Pancreas
- Ovaries
- Testes
Out of the above list, some glands are gender specific like testes (in males) or ovaries (in females). Glands such as the hypothalamus and pituitary glands are neuroendocrine organs.
Hormones are chemicals that affect many bodily functions ranging from hunger, reproduction, and growth to much more complicated functions like human emotions and behavior. These endocrine glands belong to the body’s control system and they produce hormones that help to regulate the functions of cells and tissues.

So, the correct answer is option A.



Note:Endocrinology is the study of the endocrine system and its disorders. Though hormones are present in very minute quantities in the human body, they play a significant role in the body's functioning.
