Question

Define endocrine gland.

Answer 1

Hint: They are the ductless glands of the endocrine system which secretes their products and hormones directly into the blood.

Complete answer:
The system is formed of a network of glands. These glands secrete hormones to control several bodily functions, as well as growth and metabolism.
While several elements of the body build hormones, the foremost glands that frame the system square measure are

>Hypothalamus- It is known as the master gland. The neural structure is understood because the master plugboard as a result of it is a part of the brain that controls the system. The ductless gland, that hangs by a skinny stalk from the neural structure, is termed the master secreter of the body as a result of it regulates the activity of the endocrine glands.
>Pineal gland- It is known as third eye. The endocrine gland, additionally called the 'pineal body,' may be a tiny secretory organ. it's situated on the rear portion of the third cerebral ventricle of the brain, that may be a fluid-filled area within the brain. This secreter mediates the 2 halves of the brain.
>Pituitary gland- It is known as the Master gland. The pituitary, a pea-sized secreter at the bottom of the brain, produces a variety of hormones. Every of those hormones affects a particular part of the body (an organ or tissue). As a result of the pituitary controls the operation of most different endocrine glands, it's typically referred to as the master secreter.
>Thyroid gland- The thyroid, or thyroid, is an associate secreter within the neck consisting of 2 connected lobes. The lower 2 thirds of the lobes are connected by a skinny band of tissue referred to as the thyroid isthmus.
>Parathyroid gland- Parathyroid glands square measure four little glands of the system that regulate the atomic number 20 in our bodies. ductless gland glands square measure placed within the neck behind the thyroid wherever they ceaselessly monitor and regulate blood Calcium levels.
>Thymus- The thymus may be a specialised primary bodily fluid organ of the system. at intervals the thymus, Thymus cell lymphocytes or T cells mature. T cells square measure vital to the adaptive system, wherever the body adapts specifically to foreign invaders.
>Adrenal gland- It is also known as Suprarenal gland. Adrenal glands turn out hormones that facilitate regulate your metabolism, system, force per unit area, response to fret and different essential functions. Adrenal glands area unit composed of 2 components — the cortex and therefore the medulla — that area unit every answerable for manufacturing completely different hormones.
>Pancreas - It makes exocrine gland juices that contain enzymes that aid in digestion, and it produces many hormones, together with hypoglycemic agents.
Notes:The endocrine hormones facilitate management mood, growth and development, the strategy our organs work, metabolism , and reproduction. The system regulates what amount of each endocrine is discharged.
