First time calcium was discovered in the year of 1808. Scientist Sir Humphrey Davy discovered the calcium element for the first time. calcium word originated from Latin language. In Latin the word is 'calcis', this is the basic word. Calcium was originated from calsis. Calcis means lime. Calcium can be produced from the sources of limestone, marble 3.5% of crust & chalk. Calcium can be symbolized as 'ca'. Calcium consists of 20 protons & 20 electrons & 20 neutrons. Calcium can be defined as Alkaline Earth metal. Calcium is 5th most available element on the Earth. Atomic number of Calcium is 20. Generally atomic number can be defined according to the presence of number of electrons. Calcium's density is 1.55 g/cm3 consequently boiling point & melting point of Calcium are 1484°C, 839°C. Atomic mass of Calcium is 40.078 amu. Color of Calcium is generally silver. Calcium cannot be available as element. Calcium can be generally found in rocks in the form of dolomite & gypsum & calcite.
Foods rich in Calcium
Potatoes, nuts, seeds, fruits, meats, milk, sugars, Cereals, Vegetables, Fishes, Shellfishes, Mushrooms, Algae. These above mentioned foods contain of rich amounts of Calcium.
Role of Calcium in human being body
Calcium plays a key role in all human being body's functions. Calcium is mainly essential to increase the strength of bones & teeth. Calcium is necessary in the free movements of body muscles like contractions & relaxation of muscles. Calcium plays a crucial role in the heart's function. Calcium is necessary to control blood pressure. Calcium is necessary in the function of clotting of blood, which is useful to prevent bleeding when wounds occur. If Calcium levels are insufficient, blood clotting cannot be occurred. If blood doesn't clot body looses blood continuously, it may lead to death. So Calcium is very important to clot blood & prevent bleeding. Calcium has a essential role in the function of transmitting of nerve impulses. Calcium has essential role in the activation of different enzymes. these enzymes take part in the metabolism, digestion & energy generation. These are the crucial functions in the human beings body which are related with Calcium availability. Calcium has a crucial role in boosting of immune system & protecting periodontal disorders. Calcium is very necessary for pregnant and lactating women. Calcium promotes uterus contractions in the child birth & synthesis of milk. Calcium is useful in the discharge of different hormones which lead to proper activation of different enzymes.
Symptoms of Calcium deficiency
Deficiency of Calcium leads to the bone problems which can be defined as osteoporosis. Decreases in the Calcium levels causes bone breakages. Generally 99% of calcium is accumulated in the Bones & Teeth. When Calcium levels decrease in the human beings body, body regains calcium from bones. So bones get weakened. It leads to the breakages of bones easily. This condition is called osteoporosis. Serious deficiency of Calcium can be called as hypocalcemia. It occurs due to the high insufficiency of calcium in the blood stream. Insufficiency of calcium leads to tetany. Symptoms of tetany is pains in the muscles, itching near the mouth & finger tips and lack of sensation.
