What is calcium and its function?
Calcium is a mineral most often associated with healthy bones and teeth, although it also plays an important role in blood clotting, helping muscles to contract, and regulating normal heart rhythms and nerve functions.
What is the concentration ppt of calcium?
The most abundant salts are sodium chloride (NaCl, 29.536 ppt), sulphate (SO4, 2.649 ppt), magnesium (Mg, 1.272 ppt), calcium (Ca, 0.400 ppt) and potassium (K, 0.380 ppt) (Riley and Skirrow 1965, Open University Course Team 1995).
What are the regulator of calcium in body?
The specific calcium regulating hormones, parathyroid hormone, calcitriol and calcitonin, affect calcium and phosphorus concentration and supply by acting on bone, kidney and intestine.
What is the deficiency condition of calcium?
Hypocalcemia (Calcium Deficiency Disease)
What are 5 benefits of calcium?

What are 5 uses of calcium?
People commonly take calcium by mouth for the treatment and prevention of low calcium levels, muscle cramps, osteoporosis, softening of the bones, and PMS. It is also used for high blood pressure, cancer, stroke, and many other conditions, but there is no good scientific evidence to support many of these other uses.
How do you calculate calcium content?
This method, called a complexometric titration, is used to find the calcium content of milk, the ‘hardness’ of water and the amount of calcium carbonate in various solid materials. The method uses a very large molecule called EDTA which forms a complex with calcium ions.
How is calcium metabolism?
Calcium metabolism mainly depends on the activity of parathyroid hormone (PTH). Its secretion is strictly controlled by the ionized serum calcium levels through a negative feed-back, which is achieved by the activation of calcium-sensing receptors (CaSRs) mainly expressed on the surface of the parathyroid cells.
What produces calcium in the body?
Besides building strong bones and teeth, calcium helps muscles contract and nerves transmit signals. Normally, if there isn’t enough calcium in your blood, your parathyroid glands secrete a hormone that triggers: Your bones to release calcium into your blood.
What is the source of calcium?
Sources of calcium include: milk, cheese and other dairy foods. green leafy vegetables – such as curly kale, okra but not spinach (spinach does contain high levels of calcium but the body cannot digest it all) soya drinks with added calcium.

What are the factors that affect calcium balance?
Calcium deficiency in the blood is controlled by parathyroid hormone. Various factors such as age, sex, nutritional condition, illness and prescribed medication affect the Calcium metabolism and therefore Calcium balance. 9. Age factor Calcium deficiency increases with age.
