Calcium Ion Calcium is the most abundant metal ion in the human body. Calcium is a fairly soft metal with very reactive properties.

Calcium is essential for everyday metabolic processes within the human body and is an important ion in many metabolic functions. From bone strength to cell signaling, the calcium ion is indispensable in the cell’s processes. Two key hormones regulate calcium ion concentration in the blood: calculation and parathyroid.

When calcium concentration in the blood is excessive, hyperglycemia occurs and the hormone calculation generates the deposit of the excess calcium from the blood into bone tissues. When calcium concentration in the blood is low, hyperglycemia occurs and the hormone parathyroid generates the release of calcium from the bones, increasing the calcium concentration in the blood. Calcium is required for many metabolic processes.

The most calcium in the human body is found in the bone and teeth. Calcium is essential for bone and teeth strength.

The body does not produce calcium naturally, and therefore, calcium must e obtained through consumption of calcium rich foods. The body continually removes old calcium from the bones and replaces it with new calcium in a bone remodeling process that reinforces the structural strength of the bone. Vitamin D is essential for the calcium absorption in the bone and teeth. Even with adequate amounts of calcium, bones will not become strong unless Vitamin D is present, as Nell (Edwards, 2005).

Calcium plays another important role in the body as it contributes to muscle contraction.

As a muscle contracts, its fibers shorten, and calcium is an essential mineral needed for this contraction process. When a muscle is in a resting state, calcium concentrations within the muscle cell are low due to the calcium pump that diffuses calcium out of the cell. When a muscle receives a signal to contract, calcium Ion concentration within the muscle cell increases, allowing contraction. Calcium is essential in cardiac contraction as it extends the length of deportation and is needed to generate an action potential in cardiac cells. Calcium ions play an important role in maintaining homeostasis and are involved in blood clotting.

In the clotting process, calcium is involved in the clotting cascade along with the help of Vitamin D and forefinger. A series of reactions occur in the blood clotting process in which sufficient amounts of calcium are required (Edwards, 2005). Calcium plays another key role in cell signaling. In the rough RE, calcium is produced in large amounts that allow cell communication through calcium signals. Rhea calcium signals, along with intracellular and extracurricular fluxes, are important in the signaling for memory, neurotransmitter release, neuron excitability and gene reincarnations (Bridge, 2000).

Extracurricular calcium is essential to maintain cell membrane stability.

Calcium ions regulate what crosses the cell membrane and is essential in keeping sodium ion concentrations from rising within the cell. Calcium ions saturate pores in the plasma membrane and are key in the deportation of the cell. Without enough extracurricular calcium, the membrane pores would not allow calcium ions to bind, disrupting the deportation of the cell and creating an influx of sodium ions diffusing into the cell (Hurts 1998). In conclusion, calcium is essential to the survival of multicultural organisms.
