The three target organs of parathyroid hormone are bones, kidneys, and intestines. Parathyroid hormone acts on these organs to regulate calcium levels in the body by increasing calcium absorption in the intestines, promoting release of calcium from bones, and reducing calcium excretion in the kidneys.
Parathyroid harmone acts on bone,kidney and intestine. It basically causes increase in serum calcium levels and decrease serum phosphorous levels.It causes bone resorption which increases serum calcium level,it acts on kidney causing increased excretion of phosphorous there by decreasing serum phosphorous levels.Its action on intestine is indirect through vitamin-D which increases intestinal absorption of calcium.
Anterior pituitary hormones target the gonads, thyroid, liver, fat cells, adrenals, and breasts. In addition, endorphins target the pain receptors.

What role do calcium play in homeostasis?
Three hormones: parathyroid hormone, calcitonin and 1,25 dihydroxycholecalciferol (the active from of Vitamin D). These three hormones act on bone, the kidneys and the small intestine to keep calcium balance in you r body.
What hormone does the parathyroid release?
The parathyroid gland releases parathyroid hormone (PTH), which regulates calcium levels in the blood by acting on the bones, kidneys, and intestines. PTH helps to increase blood calcium levels by promoting calcium release from bones and reducing calcium excretion by the kidneys.
What are three body organs?
Three body organs are: the brain, the heart, the liver.
What are three conditions related to alterations in growth hormone?
Acromegaly: a disorder where the pituitary gland produces too much growth hormone, leading to excessive growth of tissues and organs. Dwarfism: a condition characterized by a lack of growth hormone production, resulting in short stature. Gigantism: a condition caused by an overproduction of growth hormone before puberty, leading to excessive growth and height.
What are three ways in which endocrine glands are stimulated to secrete their hormones?
· Hormonal stimuli - the most common; endocrine organs are prodded into action by other hormones. Hormone release promoted by this mechanism tends to be rhythmic, with hormone blood levels rising and falling again and again · Humoral Stimuli - changing blood levels of certain ions and nutrients stimulate hormone release. Humoral refers to humor to indicate the various body fluids (blood, bile, etc). · Neural Stimuli - In isolated cases, nerve fibers stimulate hormone release, and the target cells are said to respond to neural stimulus. The classic example is sympathetic nervous system stimulation of the adrenal medulla to release norepinephrine and epinephrine during periods of stress.
What are three target organs of parathyroid hormone?
Bones, kidneys, small intestine.The classical target organs for parathyroid hormone (PTH) are the bone and kidneys. In uremia, however, numerous studies have shown that PTH may also affect the function of a number of nonclassical organs and tissues besides the bone and kidney, including the brain, heart, smooth muscles, lungs, erythrocytes, lymphocytes, pancreas, adrenal glands, and testes.
What role do calcium play in homeostasis?

Which hormone stimulates osteoclasts in the raising of calcium levels in the blood?
If you are looking for the one hormone that does this, then the answer is parathyroid hormone (PTH), produced in the parathyroid glands.A more technical description is given below:Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands. The first, 1,25-Dihydroxycholecalciferol (active vitamin D3), serves to increase calcium absorption from the intestine. The second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed ("reabsorbed") into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.References: Ganong's Review of Medical Physiology, 23eKim E. Barrett, et. al.

What hormone does the parathyroid release?
The parathyroid gland releases parathyroid hormone (PTH), which regulates calcium levels in the blood by acting on the bones, kidneys, and intestines. PTH helps to increase blood calcium levels by promoting calcium release from bones and reducing calcium excretion by the kidneys.
Parathyroid glands belong to which organ system?
The parathyroid glands belong to the endocrine organ system. This system is comprised of different glands in the body including (but not limited to) the thyroid gland, the parathyroid glands, the pituitary gland, the gonads as well as the pancreas. The parathyroid glands produce parathyroid hormone, and help regulate the amount of calcium in the blood - which in turn governs the amount of calcium in the bones of the body.
The three factors most responsible for regulating calcium levels?
The three main factors responsible for regulating calcium levels in the body are parathyroid hormone (PTH), vitamin D, and calcitonin. PTH increases calcium levels in the blood by promoting its release from bones and increasing its absorption in the intestines. Vitamin D assists in calcium absorption in the intestines, while calcitonin helps to lower blood calcium levels by inhibiting bone breakdown.
What hormone increases blood calcium hormones?

What are three body organs?

What are the three endocrine organs located in the abdominal cavity of the cat?
The three endocrine organs located in the abdominal cavity of the cat are the pancreas, adrenal glands, and the ovaries or testes.
What are three conditions related to alterations in growth hormone?
Acromegaly: a disorder where the pituitary gland produces too much growth hormone, leading to excessive growth of tissues and organs. Dwarfism: a condition characterized by a lack of growth hormone production, resulting in short stature. Gigantism: a condition caused by an overproduction of growth hormone before puberty, leading to excessive growth and height.
What are the three lobes?
Several organs have three lobes.
