Endocrine System - Coggle Diagram
Endocrine System
Name Of Organs
Adrenal Glands
Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.
-

-
Pineal Body
The main function of the pineal gland is to receive and convey information about the current light-dark cycle from the environment and, consequently produce and secrete melatonin cyclically at night (dark period).
Secretes Melatonin
Melatonin also functions as an antioxidant in the body. It is very effective in protecting against infection, inflammation and immune system diseases.
Parathyroid
Role of Parathyroid
The parathyroid glands produce parathyroid hormone. This hormone helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning.
Scretes Parathormone
Increases the amount of calcium in oıur blood cells.And also it makes the bones to secrete the Calcium
The Ovaries
The ovaries produce and release eggs (oocytes) into the female reproductive tract at the mid-point of each menstrual cycle. They also produce the female hormones oestrogen and progesterone.

-
Thyroid
Role Of Thyroid
The thyroid is part of the endocrine system, which is made up of glands that produce, store, and release hormones into the bloodstream so the hormones can reach the body's cells.
The thyroid gland uses iodine from the foods you eat to make two main hormones: Triiodothyronine (T3) Thyroxine (T4)

-
The Testes
The two main functions of the testes are to produce sperm and to produce the male sex hormones (androgens). This makes the testis both an endocrine and exocrine gland (which release substances into a duct rather than directly into the blood like endocrine glands)
Pituitary Gland
Role Of Pituitary:
The pituitary gland is a part of your endocrine system. Its main function is to secrete hormones into your bloodstream. These hormones can affect other organs and glands.
-
Hypotalamus
Role Of Hypotalamus:
The hypothalamus links the nervous and endocrine systems by way of the pituitary gland. Its function is to secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
Pancreas
Pancreas regulates blood glucose levels.Also the pancreas consists of islet cells (islets of Langerhans) that create and release important hormones directly into the bloodstream.

Disease
Multiple sclerosis
In MS , the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body.
Diabetes
Diabetes affects how the body regulates blood glucose levels. Insulin helps to reduce levels of blood glucose whereas glucagon's role is to increase blood glucose levels. In people without diabetes, insulin and glucagon work together to keep blood glucose levels balanced.
Rickets
Rickets is a long-term and excessive vitamin D deficiency in children. Rickets causes the bones of children to soften and weaken. Sometimes, although rare, hereditary problems can cause rickets.
Feedback Mechanism
Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range.
For example
When the thyroxine level in our body increases the feedback mechanism (which is negative
feedback) activates and synapes to
the anterior gland to stop secreting TSH.And makes the hypotalamus to stop stimulating to the anterior gland.
The Major Function Of Endocrine System:
The endocrine hormones help control mood,
growth and development,the way our organs work, metabolism,and reproduction.And it also regulates how much of each hormone is released.
-
Antagonistic Mechanism
example of antagonistic hormones occurs in the maintenance of Ca 2+ concentration in the blood. Parathyroid hormone (PTH) from the parathyroid glands increases Ca 2+ in the blood by increasing Ca 2+ absorption in the intestines and reabsorption in the kidneys and stimulating Ca 2+ release from bones.
