SKELETAL SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Must be present in the blood at all times for the nervous system to transmit messages, for muscles to contract, and for blood to clot:
A
calcium
B
adipose tissue
C
phosphorus
D
iodine
Explanation: 

Detailed explanation-1: -The PTH system provides long-term, day-to-day regulation of calcium levels by many hormones working in concert. This hormonal “feedback loop” is governed by the parathyroid glands and the calcitonin-secreting cells of the thyroid gland by their constant monitoring of the blood calcium levels.

Detailed explanation-2: -#Sign 4 – Blood Clots A high deficiency can also form blood clots which reduce blood flow. When you sustain a minor injury, blood will form easily, and the blood clot forms slowly. This risks the chance of more blood flow release. Calcium has a strong link to blood clotting.

Detailed explanation-3: -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.

Detailed explanation-4: -Calcium is transported through the bloodstream as dissolved ions or bound to proteins such as serum albumin. Parathyroid hormone secreted by the parathyroid gland regulates the resorption of Ca2+ from bone, reabsorption in the kidney back into circulation, and increases in the activation of vitamin D3 to calcitriol.
