Sentences with phrase «blood calcium concentrations»

Vitamin D is a hormone the kidneys produce that controls blood calcium concentration and impacts the immune system.

True calcium deficiency is rare, because blood calcium concentrations are maintained at the expense of bone calcium.

While this complex system allows for rapid and tight control of blood calcium concentrations, it does so at the expense of the skeleton (1).

A slight increase in blood calcium concentration stimulates the production and secretion of the peptide hormone, calcitonin, by the thyroid gland.

Other, but rarer, causes of metastatic calcification include kidney disease (this is the most common cause in cats), malignant tumors producing abnormal hormones that increase blood calcium concentrations (e.g. tumors of the lymphoid system and glands of the anal sac), diabetes mellitus and lung disease.

Finally, acute changes in blood calcium concentrations do not seem to elicit the secretion of the phosphaturic hormone fibroblast growth factor 23 (FGF - 23), which is produced by bone - forming cells (osteoblasts / osteocytes) in response to increases in phosphorus intake (see the article on Phosphorus)(2).

The physiological functions of calcium are so vital to survival that the body will stimulate bone resorption (demineralization) to maintain normal blood calcium concentrations when calcium intake is inadequate.

A slight drop in blood calcium concentration (e.g., in the case of inadequate calcium intake) is sensed by the parathyroid glands, resulting in their increased secretion of parathyroid hormone (PTH).

Calcium absorption in the intestinal tract of rabbits is much higher than in other species and does not depend on vitamin D, so high - calcium diets may lead to increased blood calcium concentrations.

Because there is a small risk that temporary interference with calcium regulation may occur, it is usually recommended that cats remain hospitalised for a few days after surgery, and blood calcium concentrations are monitored during this time.

Calcinosis cutis develops in some animals but not others, even though they have similar steroid hormone or blood calcium concentrations.

The parathyroid glands are responsible for maintaining this delicate balance and keeping the blood calcium concentration within an optimal range.
