Why do bone have increased calcium and phosphate levels due to exercise?

This is a good question! The calcium and phosphate level increase due to exercise. This is physiological response to stress of exercise. Your bones and muscles develop due to exercise. The bones becomes stronger and stronger as you give more and more stress to them. The stress lines also change as per requirement of the stress. Your bones get weak, when you put a plaster for fracture. This happens due to disuse of the bones.

What hormone controls levels of calcium in blood and helps maintain balance of phosphorus?
Parathyroid hormone (PTH), released by the parathyroid gland; and calcitonin, released by the thyroid gland, control the levels of phosphorus in the body. Most of the phosphorus in the body is stored in the form of phosphate (PO4) attached to calcium in the skeletal systems to form calcium phosphate [Ca3(PO4)2]. When PTH is released, excess phosphate is released into the urine and calcium is released from the skeletal system into the bloodstream. The calcitonin plays its part by helping form calcium phosphate molecules, where they become part of a mineral matrix in the bone. Because of the relationship between PTH and calcitonin, calcium and phosphate maintain proportionally inverse levels in the blood.
When calcium blood levels fall a gland in the body releases a special hormone?
Its the hormone calcitonin. Calcitonin lowers calcium and phosphate and increases the excretion of these ions by the kidneys; whereas the parathyroid hormone increases the amount of calcium in the blood.
Decreased blood calcium levels would result in?
When blood calcium levels are low, it means that calcium is not being reabsorbed in the intestine or released from the bones. This could lead to uncontrollable twitching, known as a disorder called tetany, caused by low blood calcium levels.
Cells that free calcium from bone to maintain blood calcium levels are called?
osteoblasts
How are calcitonin parathyroid hormone and vitamin D in maintaining blood calcium levels?
The sole function of the parathyroid glands is to maintain the body's calcium level within a very narrow range, so that the nervous and muscular systems can function properly. When blood calcium levels drop below a certain point, calcium-sensing receptors in the parathyroid gland are activated to release hormone into the blood. Parathyroid Hormone (PTH, also known as parathormone) is a small protein that takes part in the control of calcium and phosphate homeostasis, as well as bone physiology. PTH has effects antagonistic to those of calcitonin. PTH increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium. PTH also increases gastrointestinal calcium absorption by activating vitamin D, and promotes calcium uptake by the kidneys.
Is calcium phosphate soluble?
No, calcium phosphate is insoluble. This is why calcium levels are kept low inside the cytoplasm (eukaryotic cells).
How is Phosphorus imbalance observed?
Disorders of phosphate metabolism are assessed by measuring serum or plasma levels of phosphate and calcium
The parathyroids are responsible for regulating proper levels of which elements in the blood?
phosphate and calcium
What is the function of parathyroid hormone?
PTH is secreted by the parathyroid glands (which are attached to your thyroid) and acts on bone (via increased bone resorption) , the kidneys (via increased reabsorption of calcium) and the intestine (increased calcium absorption by increased levels of activated vitamin D) to increase blood calcium levels.
What hormone controls levels of calcium in blood and helps maintain balance of phosphorus?

Which is greater when blood calcium levels when parathyroid hormone is increased or decreased?
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
Why is calcium-vitamin d taken?
Milk is fortified with vitamin D that helps with the absorption of calcium. This supports phosphate levels leading to healthier bones.
What is the relation of 'steroid suppression test' with parathyroid gland?
My impression is that the steroid suppression test (Dexamethasone test) is to help differentiate between primary hyperparathyroidism from hypercalcaemia secondary to increased corticosteroids levels. Idea 1: corticosteroids reduce calcium and phosphate absorption and inhibits bone formation (this is the catabolic arm of the cortisol stress response). Therefore, if there is a high level of corticosteroids, the result would be decreased serum calcium and phosphate. Idea 2: Lowered serum calcium and phosphate levels would in turn upregulate parathyroid hormone production to increase serum calcium and phosphate levels caused by Idea 1. Idea 3: A patient with hypercalcaemia could be given a steroid suppression test. If the hypercalcaemia were secondary to the steroids, then one would expect a responsive lowering of parathyroid hormones.
What parathyroid hormone increases serum calcium levels?
PTH activates vitamin D in the body, which absorbs calcium and phosphate from foods. It works on the intestine to increase the absorption of calcium. It causes the bones to release more calcium, and causes the kidneys to reabsorb more calcium. This all helps to increase calcium levels.
What organs does The Parathyroid Hormone Affects?
It controls the phosphate and calcium levels. So mainly affect on intestine ans bones.
What is calcium build up in the body?
In order to lower your calcium levels in your body you can do a few things. Calcium is used by muscles in the human body so you can exercise and utilize some of the calcium which you have building up. You can also lower the amount of calcium you get per day and increase your fluids. Also talk to your DR. about meds that lower calcium levels such as loop diuretics, and corticosteroids.
What is Tertiary hyperparathyroidism?
Tertiary hyperparathyroidism occurs when CRF causes a severe imbalance in the calcium-phosphate ratio, leading to very high PTH production that results in hypercalcemia. Patients with this condition have high PTH and high calcium levels.
