Transcript of Endocrine System.

The Endocrine system which coordinates and regulates functions such as growth,development,
metabolism and reproduction". (“The Endocrine system” by Stephanie Watson and Kelli Miller) . There are 9 major parts of the Endocrine system.

The Endocrine System is a very important part of the human body!

What is the Endocrine System?
Endocrine System.
There are 9 major parts of the Endocrine System.
Hypothalamus,Pituitary Glands,Thyroid Glands, Parathyroid,Pancreas,Thymus,Ovaries,
Adrenal Glands, Testes .
How important is the Endocrine system to the human body?

Mini Question # 1
Hormones are produced by various tissues, lipids, protein. Hormones are produced by nearly every organ system.The purpose of of hormones is that they are to be a signal to the ‘target cell’.Hormones are the chemical messengers of the Endocrine system

Answer # 6
What role does the endocrine system have during the menstrual cycle?
The Endocrine System influences close to all organs, cell, and function in our bodies. The endocrine assists sexual and tissue functions as well as metabolism and the reproductive process.
The Endocrine system consists of hormone glans. Hormones are secrete from these glands and used to transfer information and instructions.
Answer :
-Growth hormone: This hormone promotes growth in childhood. For adults, it helps to maintain healthy muscle and bone mass.
-Prolactin: In women, it stimulates milk production. In males, low levels are linked to sexual problems; however, most males make no use of the hormone.
-Adrenocorticotropic: This hormone promotes the production of cortisol, which helps to reduce stress, maintain healthy blood pressure and more.
-Thyroid-stimulating hormone: Just as the name implies, this hormone helps to regulate the body's thyroid, which is crucial in maintaining a healthy metabolism.
-Luteinizing hormone: In women, this hormone regulates estrogen. In men, it regulates testosterone.
-Follicle-stimulating hormone: Found in both men and women. It stimulates the releasing of eggs in women and helps ensure the normal function of sperm production in men.
The back part of the pituitary gland is called the posterior pituitary. It produces the following two hormones:
-Oxytocin: This hormone causes pregnant women to start having contractions at the appropriate time and also promotes milk flow in nursing mothers.
-Antidiuretic hormone: Commonly referred to as vasopressin, this hormone helps to regulate water balance in the body.
Regulates hunger thirst, sleep and wakefulness plus most involuntary mechanism including body temperature.
Pituitary Glands
- Controls all other Endocrine Glands influences growth, metabolism, and regeneration.
Thyroid Glands
- Regulates your energy and your metabolism.
Parathyroid- Secretes the hormones necessary for calcium absorption.
- Aids in the digestion of protein , fats and carbohydrates. produces insulin which controls blood sugar levels.
- Helps build resistance to diseases.
- Influences how your blood circulates and determines your mental vigor and your sex drive.
Adrenal Glands
- Secretes hundreds of compounds including cortisone & adrenaline which helps you react to emergencies. Regulates your metabolic process in the cells , water, balance, blood pressure, etc.

Adrenal Glands
Pineal Gland
Aging affects a woman's ovaries and results in menopause, usually between 50 and 55 years of age. In menopause, the ovaries stop making estrogen and progesterone and no longer have a store of eggs. When this happens, menstrual periods stop.
All this happens in the endocrine system.
Pituitary Gland
It greatly influences other organs in the body, and its function is vital to the overall well-being of a person. The pituitary gland produces several hormones.Growth hormone, Prolactin, Adrenocorticotropic,Thyroid-stimulating hormone,Luteinizing hormone,Follicle-stimulating hormone, Oxytocin, Antidiuretic hormone
Hypothalamus-The hypothalamus is in control of pituitary hormones by releasing the following types of hormones:
- Thyrotrophic-releasing hormone
- Growth hormone-releasing hormone
- Corticotrophin-releasing hormone
- Gonadotropin-releasing hormone
Thymus-This gland secretes hormones that are commonly referred to as humeral factors and are important during puberty. The role of these hormones is to make sure a person develops a healthy immune system.
Pituitary Gland
Found in men, this gland produces testosterone, which promotes the growth of the penis as a male gets older as well as facial and body hair. It also deepens the voice of a male at a certain age. Other functions of testosterone include:
- Maintaining sex drive
- Promoting production of sperm
- Maintaining healthy levels of muscle and bone mass
Found in women, this gland produces both estrogen and progesterone, which promote the development of breasts. They also help a woman maintain healthy menstrual periods.
Found in both women and men, the thyroid controls a person's metabolism. It is located in the front of the neck.
This gland helps to control blood sugar. In addition, also helps your body do the following:

- Promoting proper cardiovascular function
- Properly utilizing carbohydrates and fats
- Helps distribute stored fat
- Promotes healthy gastrointestinal functions
This gland is vital to proper bone development because it helps control both calcium and phosphorous levels in the body. The parathyroid gland is actually a group of four small glands located behind the thyroid gland.
The main function of the pancreas is to maintain healthy blood sugar levels. It is a large gland located behind the stomach.
The main function of the endocrine system is to serve as our body’s message center. The endocrine system is made up of endocrine glands. These glands secrete hormones into our blood or surrounding interstitial fluid. . Hormones deliver messages, the endocrine system coordinates hormones..

Our endocrine system works closely with our nervous system to maintain proper function. Most body organs are influenced by the nervous system and the endocrine system. The nervous system sends messages through nerve impulses .While the endocrine system sends hormones as messages.

Without proper endocrine function, our bodies cannot maintain proper hormonal balance. The health of our endocrine system is essential to our ability to function properly. Our cells are genetically programmed to only receive and respond to messages from certain hormones. Hormone levels can be influenced by stress, fluid changes in the body, minerals in the blood and infection. Each endocrine gland plays a specific role in the ability of our body to maintain proper function. Each endocrine gland also communicates with the other in an amazing design. If one of the endocrine glands is not functioning properly, it may cause a broken link in communication with other endocrine glands or actions of the body, which may greatly impair fertility. Because the endocrine glands secrete hormones, and the hormones are messengers for actions within the body, if the gland is not functioning properly, hormonal imbalance occurs and the ability to reproduce may be impaired
The endocrine system is a system that is in charge of hormones.
Interstitial fluid
Interstitial fluid (or tissue fluid) is a solution that bathes and surrounds the cells of multi-cellular animals. It is the main component of the extracellular fluid, which also includes plasma and transcellular fluid. The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces.
Metabolism~The chemical processes that occur within a living organism in order to maintain life.
Estrogen~Any of a group of steroid hormones that promote the development and maintenance of female characteristics of the body.
A steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.
A steroid hormone released by the corpus lutetium that stimulates the uterus to prepare for pregnancy.
Estrogen~Any of a group of steroid hormones that promote the development and maintenance of female characteristics of the body.
