Atrial Natriuretic Factors
hormones released by the hear when blood pressure increases, they stimulate the kidneys to produce more urine which reduces the fluid volume in the blood, which reduces blood pressure
A hormone produced by the thyroid gland that helps lower the level of calcium in the blood
A hormone secreted by the adrenal glands that raises blood glucose levels and increases blood volume and blood pressure when the body is under stress; cortisol also suppresses the immune system
Also called salts, they are charged particles dissolved int he body's water that are crucial to the body's proper functioning (e.g. nerve impulses, the contraction of muscles, and maintaining fluid balance in the body). Sodium, Magnesium, Potassium and Chloride are the most important electrolytes
Hormones secreted by the pituitary gland that reduce the perception of pain
also known as adrenaline, it is a hormone released by the adrenal glands during periods of stress , epinephrine increases heart rate and the supply of oxygen to the blood and glucose to the brain and muscles suppressing other functions, thus creating the "fight-or-flight" response
A hormone produced by the kidneys that stimulates red bone marrow to produce more red blood cells
hormones that produce female characteristics
A hormone secreted by the islets of langerhans in the pancreas that raises blood glucose levels
A sugar molecule that provides cells with energy
A Form of Glucose that is stored in the liver and muscle cells. When blood glucose level drops, glycogen will stimulate the liver and muscles to convert the glycogen to glucose
Glands, such as the ovaries and testes, that produce sex hormones
Also called somatotrophin, it is a hormone produced by the pituitary gland that stimulates protein synthesis in bone and muscle, as well as the use of fat as fuel
Chemical "messengers" secreted by glands of the endocrine system. Hormones circulate through the bloodstream to other organs and tissues to effect the processes of growth, metabolism, sexual function, and mood. Hormones are chemically classified as either steroids or non-steroids (which includes protein hormones and peptide hormones)
An almond-sized organ of the endocrine system located near the center of the brain. The Hypothalamus links the nervous and endocrine systems. It regulates body temperature , sleep cycle, appetites, and sexual behavior; it also controls the pituitary gland.
A hormone produced in the pancreas that regulates the amount of sugar in the blood but triggering the conversion of glucose to glycogen, which lowered the blood glucose level
Islets of Langerhans
Clusters of cells in the pancreas that produce glucagon (secreted by alpha cells) and insulin (secreted by beta cells)
Located at the back (Dorsal Side) of the abdominal cavity, that produce renin, a hormone that ultimately helps regulate blood pressure, and erythropoietin, a hormone that stimulates red bone marrow to produce more red blood cells
Adrenocorticotropic Hormone, a hormone that stimulates the release of cortisol
Organs of the endocrine system located above the kidneys. the adrenal glands secrete cortisol, epinephrine, and nor epinephrin.
A type of non steroidal hormone, such s that produced by the thyroid gland.
A form of testosterone used to enhance muscle development and performance
A hormone, such as testosterone, that regulates the development of male characteristics
A type of compound that is fat soluble, meaning it can pass through cell walls. Lipids must combine with protein molecules (forming lipoproteins) in order to travel through the blood.
A hormone secreted by the pineal gland
A chemical classification of hormones which is usually broken up into two types: amines and peptides. Peptides are sometimes also called "polypeptides" or "protein hormones", and include insulin and growth hormones. Non steroid hormones are water soluble.
Also known as noradrenaline, it is a hormone that is real eased by the adrenal glands during periods of stress. Norepinephrine causes the response known as "fight-or-flight".
An organ of the endocrine system located beneath the stomach, it secretes the hormones insulin and glucagon.
Four small tissue masses attache to the back of the thyroid, they secrete parathyroid hormone, which raises blood calcium levels.
One of three that help regulate calcium levels in the body
A pea sized organ of the endocrine system located slightly above and behind the hypothalamus; near the center of the brain. The pineal gland receives information about light and dark cycles; it (the pineal gland) secretes melatonin which is involved in helping the body maintain rhythmic behavior such as sleep cycles.
A pea-sized organ of the endocrine system. Located on the underside of the brain, it secretes hormones that regulate homeostasis, as well as hormones that stimulate other endocrine glands. The anterior pituitary releases growth hormone and endorphins, the posterior pituitary secretes oxytocin sand vasopressin.
A hormone produced by the kidneys that ultimately helps regulate blood pressure.
A process in which a hormone attaches to a receptor protein on a cell, whereupon the receptor causes a specific change to happen inside the cell.
A type steroid that acts as a hormone. Steroid hormones are formed from cholesterol, and are lipids. Estrogen, progesterone, and testosterone, and cortisol are all steroid hormones; certain forms of vitamin D are also grouped with steroid hormones.
In endocrinology, a cell that has specific receptor to which specific "matching" hormones can bind.
A hormone that produces male characteristics
A chemical produced by the thymus gland that activates lymphocytes (White Blood Cells), cells that are involved in battling infection
A gland of the endocrine system that is located in the thoracic region that produces thymosin.
A gland of the endocrine system located in front of the trachea, it releases thyroid hormone, which plays a cortical role in development and growth. The thyroid gland also increases the body's metabolic rate and relies of calcitonin, a hormone that lowers blood calcium.
A hormone produced by the thyroid gland and controlled by the hypothalamus and the pituitary gland. It affects growth and development and also stimulates the metabolism of nearly every tissue in the body.
Also called antidiuretic hormone, it is a hormone released by the pituitary when the brain detects an increase in sodium concentration in the blood. Vasopressin acts on th kidneys to reduce urine output.
