The endocrine system is made up of glands which control and coordinate body functions and maintain homeostasis inside the body.
2,103 Questions
Where are your endocrine glands?
Your endocrine gland is consist of a system of glands with the main glands called the pituitary gland, pancreas, ovaries and testes, thyroid gland, and the adrenal glands.
How do substances made by endocrine glands get to other parts of the body?
endocrine glands reach their target organs because the secretion go directly to the bloodstream unlike exocrine glands that have ducts, endocrine glands secretes hormones that mix with the blood

What is the danger of having high blood calcium levels?
Hypercalcemia, high amounts of calcium in the blood, has symptoms such as nausea, vomiting, bone pain, dementia, and weakness.
Hypercalcemia is commonly caused by improper function of the parathyroid glands.
How do the endocrine glands affect growth and development?
It produces hormones that help us to grow and develop.
Which endocrine gland produces the hormone ADH?
It is called antidiuretic hormone.It controls the urine volume mainly
What are Two hormones produced by the endocrine system?
The Pituitary gland "the master gland" produces: FSH, LH, ACTH, TH, Prolatin, GH, Oxytocin, ADH and MSH.
There are many more hormones produced by the endocrine system, these are the ones produced from the "master gland"
What hormone is released into the blood when the body loses fluid?
When your body loses fluids it alters your blood pressure sending signals to your brain telling it that your BP is too low. This sends off signals to your body to try and compensate. ADH (anti-diuretic hormone) is released and prevents fluid to be excreted by the kidneys into your urine. This raises the blood pressure back up by increasing the water within it. This doesn't increase your RBCs or platelets but it just allows your blood volume to remain at a relatively normal level.
It's the anti-diuretic hormone.
What hormones does the pituitary gland release to control other endocrine glands?
The anterior pituitary synthesizes and secretes the following important endocrine hormones:
Adrenocorticotropic hormone (ACTH), release under influence of hypothalamic Corticotropin Releasing Hormone (CRH).
Thyroid-stimulating hormone (TSH), release under influence of hypothalamic Thyrotropin Releasing Hormone (TRH).
Growth hormone (also referred to as 'Human Growth Hormone', 'HGH' or 'GH' or somatotropin), release under influence of hypothalamic Growth Hormone Releasing Hormone (GHRH); inhibited by hypothalamic Somatostatin.
Prolactin (PRL), also known as 'Luteotropic' hormone (LTH), release under influence of multiple hypothalamic Prolactin Releasing Factors (PRH).
The two 'Gonadotropins';
Luteinizing hormone (also referred to as 'Lutropin' or 'LH', or in males, 'Interstitial Cell Stimulating Hormone' (ICSH)), and
Follicle stimulating hormone (FSH), both released under influence of Gonadotropin Releasing Hormone (GnRH).
and;
melanocyte-stimulating hormones (MSH's) or "intermedins" as these are released by the pars intermedia which is "the middle part"; adjacent to the posterior pituitary lobe, pars intermedia is a specific part developed from the anterior pituitary lobe.
The posterior pituitary stores and releases:
Oxytocin, most of which is released from the paraventricular nucleus in the hypothalamus
Antidiuretic hormone (ADH, also known as vasopressin and AVP, arginine vasopressin), the majority of which is released from the supraoptic nucleus in the hypothalamus
Do you have to reset your hypothalamus gland with medications?
No; normal, healthy individuals without a disease affecting their hypothalamus do not need to "reset" their hypothalamus with medications. Only in certain disease states do patients need to take medications to alter the function of the hypothalamus.
The hypothalamus has exquisite control over many regulatory functions of the body. These include hunger, day/night cycles, basal metabolic rate, growth, fertility, pregnancy, sexual behavior, temperature, etc. In most individuals, the hypothalamus does a marvelously good job at regulating these functions without any need for medication. In fact, trying to "reset" the hypothalamus with medications when it isn't necessary can actually lead to more harm than good.
What are the hormones released by the adrenal gland?
the medulla- adrenaline (epinephrine), noradrenadaline(norepinephrine), dopamine cotex- three layers, zona glomerulosa- aldosterone zona fasiculata- glucocorticoids like cortisol zona reticuaris- adrogens like testosterone
Adrenal hormones: Cortisol, norepinephrine and epinephrine.
What is the inner portion of the adrenal gland is the?
The adrenal medulla is the inner portion of the adrenal gland.
Is the ovary an endocrine gland?
It is both, actually.
A gland is an organ that secretes a substance. In the case of the ovary, it secretes estrogen and progesterone in response to FSH and LH from the pituitary.
As an organ, the ovary produces the hormones above (glandular function), but also houses and matures the ova responsible for reproduction.
Low functioning thyroid (hypothyroidism) can cause weight gain by slowing down the body's metabolism. It also causes other symptoms such as sensitivity to cold (getting cold easily), dry/brittle hair, constipation, and heavy periods. This condition can only be diagnosed with a blood test looking at levels of thyroid hormones. If one's thyroid is low, they can take thyroid supplementing hormones, which will cause them to lose weight. However, it is important not to take any more medication than is necessary to regulate the hormone, because it can be dangerous (for example, causing an irregular heart beat). If the problem with the thyroid is overfunctioning (hyperthyroidism), symptoms are weight loss, racing heart, sweating, and anxiety.
Who should not have a thyroid biopsy?
A patient with a bleeding disorder should not have a biopsy unless the bleeding problem can be corrected by a transfusion of the cells that cause blood to clot (platelets).
Can drink if you take thyroid medication?
Don't take anythyng that could exite the body before of after taking thyroid medication. Wait at least 2 hours. You should be taking your medecine at the exact time and with the exact condition. You should be eating at specific times for example
What is a hormone produced by adrenal glands?
The adrenal glands consist of the adrenal cortex and the adrenal medulla, which perform separate functions.
The adrenal cortex, the outer portion of the adrenal gland, secretes hormones that have an effect on the body's metabolism, on chemicals in the blood, and on certain body characteristics. The adrenal cortex secretes corticosteroids and other hormones directly into the bloodstream. The hormones produced by the adrenal cortex include:
· corticosteroid hormones
o hydrocortisone hormone - this hormone, also known as cortisol, controls the body's use of fats, proteins, and carbohydrates.
o corticosterone - this hormone, together with hydrocortisone hormones, suppresses inflammatory reactions in the body and also affects the immune system.
· aldosterone hormone - this hormone inhibits the level of sodium excreted into the urine, maintaining blood volume and blood pressure.
· androgenic steroids (androgen hormones) - these hormones have minimal effect on the development of male characteristics.
The adrenal medulla, the inner part of the adrenal gland, is not essential, but helps in coping with physical and emotional stress. The adrenal medulla secretes the following hormones:
· epinephrine (also called adrenaline) - this hormone increases the heart rate and force of heart contractions, facilitates blood flow to the muscles and brain, causes relaxation of smooth muscles, helps with conversion of glycogen to glucose in the liver, and other activities.
· norepinephrine (also called noradrenaline) - this hormone has strong vasoconstrictive effects, thus increasing blood pressure.
IS Arthritis is due to thyroid problem?
Hypothyroidism (underactive thyroid)can cause the excessive production of uric acid. To much uric acid in the system can lead to an arthritic condition known as gout.
What affects does adrenaline have?
Adrenaline is a breakdown product of Noradrenaline. Adrenaline is a hormone which is produced by the adrenal gland in the body. Tt is produced in periods of high stress or physical activity. When the adrenal gland produces adrenaline, it causes as increase in heart rate, also dilating blood vessels and air passages. This allows for an increased volume of blood to be pumped around the body at one specific time. Also as air passages are dilated, it allows for more oxygen to be breathed in at one time; thus providing the body with more energy, and similarly allowing more Carbon Dioxide; the waste product of respiration to be exhaled at one time. Therefore it is useful during exercise as the muscle require more energy; provided by oxygen during this time. The reaction from adrenaline being produced is improved performance for short amounts of time.
Which hormone is responsible for the levels of sugar in blood?
There are several hormone which serve to raise blood glucose levels. Some examples include cortisol, epinephrine, glucagon, and growth hormone.
