Endocrine System:Discover an anatomy

 Endocrine System

Every day we can’t think about the Endocrine system, but endocrine system plays an important role for every cell, organ, and functions in body.

The Endocrine system is collection of hormone-secreting glands. Endocrine system, like digestive system is collection of different organs. And, these organs work together as one system. In such case the organs which form the endocrine system are glands. These glands secrete hormones into bloodstream. Then, blood carries out those hormones to the targeted organs and throughout the body.

The endocrine system does everything from regulate sexual function to control your good moods and bad moods. It produces the hormones you need to stay functional every day.

Main glands of the endocrine system are as:

  • Thyroid gland
  • Parathyroid gland
  • Pancreas
  • Pineal gland
  • Pituitary gland
  • Hypothalamus
  • Gastrointestinal tract
  • Ovaries
  • Testes
  • Adrenal gland

Those who study the endocrine system are called endocrinologists and the study of endocrine system is called endocrinology.

Auxiliary Endocrine Organs:

The majority of the organs recorded above are particular endocrine organs. Those organs have one fundamental occupation, and that is to deliver and emit hormones into the circulatory system.

Notwithstanding, these aren’t the main organs which discharge hormones. Other hormone-discharging organs incorporate the bone, kidney, liver, heart, and gonads. These organs, be that as it may have auxiliary endocrine capacities, and discharging hormones isn’t their essential part.

Working Procedure Endocrine Organs:

Every endocrine organ works in various ways and secretes distinctive hormones. Here’s a breakdown of how each real endocrine organ works:


The hypothalamus found in the lower focal piece of the mind. Like most organs, it’s essentially gathering of specific cells. It goes about as the fundamental connection between the endocrine and sensory systems. The hypothalamus basically goes about as the “supervisor” of the pituitary organ: it produces chemicals that instruct the pituitary organ precisely. These chemicals animate generation of hormones in the pituitary.

Pituitary gland:

The pituitary gland is small, about the measure of a pea. Regardless of its little size, the pituitary gland effectively affects the body. The pituitary is known as the “master gland” since, similar to the hypothalamus; it goes about as a manager, sending chemicals to different parts of the endocrine framework which active their production.

The pituitary gland produces all of the following hormones:

— Growth Hormone: Animates the development of bones and other body tissues.

— Prolactin: Actuates milk production in women who are breastfeeding.

— Thyrotropin: Empowers the thyroid gland to produce thyroid hormones.

— Corticotropin: Empowers the adrenal gland to produce hormones.

— Endorphins: Endorphins are chemicals which go to the sensory system, where they reduce feelings of pain.

— Sex Hormones: The pituitary in a roundabout way produces sex hormones by flagging your regenerative organs to begin making sex organs.

— Antidiuretic hormone: Controls the balance of water in the body to guarantee your cells remain hydrated.

— Oxytocin: Oxytocin triggers constrictions of the uterus when a lady is prepared to have an infant.

Either directly or indirectly, the endocrine system plays a critical role in dozens of important substantial functions.


The thyroid is another well-known organ of the endocrine system. It’s found at the front piece of your lower neck and is formed like a tie. Its principle work is to deliver two imperative hormones: thyroxine and triiodothyronine, both of which control the rate at which cells consume energizes from nourishment to create vitality.

The thyroid won’t create either hormone until the point that it gets a substance motion from the pituitary organ as thyrotropin.

You’ve most likely heard that weight reduction has a great deal to do with your thyroid gland: it’s valid! When you have a “moderate” or malfunctioning thyroid, your body won’t effectively change over sustenance into vitality: rather, it transforms that nourishment into fat.

Parathyroids :

The parathyroids are four small glands that cooperate to discharge a solitary hormone called parathyroid hormone, which controls the level of calcium in your blood. The parathyroids work synergistically with calcitonin, a hormone produced in the thyroid, to direct calcium levels in the bloodstream.

Adrenal glands :

The adrenal organs are two triangular-shaped glands found on the highest point of every kidney. They assume a vital part in our “fight or flight” reaction. Every gland produces two distinct sorts of hormones:

— Corticosteroids: These hormones regulate the salt and water that adjusts in our body while additionally controlling digestion, the resistant framework, stretch, and sexual improvement and usefulness.

— Catecholamines: Outstanding amongst other known catecholamines is epinephrine, which is otherwise called adrenaline. It controls our circulatory strain and heart rate when the body encounters push.


The pineal gland is found mid of the mind and secretes melatonin. Melatonin controls our rest cycle. The body delivers this compound when it needs us to rest.

Reproductive glands:

Both male and females have gonads, despite the fact that they work in various ways.

In males, the gonads are the testes and they secrete hormones called androgens. One of the most vital and surely understood androgen hormones is called testosterone.

In females, the gonads are the ovaries and they secrete female hormones like estrogen and progesterone.


The pancreas produces and secretes stomach related catalysts. Your body utilizes these compounds to separate sustenance as it experiences the stomach related framework. Without proteins, your body wouldn’t have the capacity to extract the vitamins and supplements it needs from the sustenance you eat.

The pancreas accomplishes something other than deliver proteins: it additionally creates two hormones called insulin and glucagon. These hormones work synergistically to control glucose, which helps your blood effectively move vitamins and nutrients (i.e. fuel) all through the body.

Problems of endocrine:

The endocrine framework isn’t great. At times, it creates issues which results in hormones to be imbalanced.

Some of the most common endocrine problems include type 1 and type 2 diabetes, which is the point at which the pancreas neglects to create enough insulin.

A few people facing hormone related issues when they’re growing up: their pituitary glands tells the bones to grow too big causing conditions like gigantism, for instance.

Two more typical endocrine issues incorporate hyperthyroidism and hypothyroidism. With hyperthyroidism, the thyroid discharges excessively numerous thyroid hormones into the blood. With hypothyroidism, the thyroid doesn’t discharge enough thyroid hormones into the blood, which means your body can’t transform food into energy. Hypothyroidism ordinarily prompts weight increase, immune system problems, and chronic fatigue.

Endocrine system versus the Exocrine system:

Try not to get confused between endocrine system and exocrine system: the two systems are similar because they both secrete hormones. In any case, the exocrine system secretes its hormones using ducts, while the endocrine system secretes its hormones into the circulatory system.

Without the exocrine system, we wouldn’t have the capacity to sweat or salivate. The exocrine system doesn’t discharge these hormones hoping to send them to the organs. Rather, it discharges these hormones for different reasons: sweat cools us down when we’re overheating. For instance, saliva contains compounds which digest the food we’re going to swallow.

The endocrine system is one of numerous frameworks which keep our body upbeat, solid, and practical. Without hormones delivered by the endocrine system, we wouldn’t have the capacity to control blood sugar, stay hydrated, reproduce, or digest the foods we eat.

Final verdict:

When your endocrine system is working properly, it produces hormones which travel through the bloodstream and arrive at their targeted organs, producing their targeted effects. The endocrine system maintains this careful balancing act all the time in an effort to keep you healthy and happy.
