Calcium is used by almost every cell in your body While most of the calcium your body has is stored in the bones and teeth each cell has its own way of storing and releasing the calcium it needs when it needs it Adults under the age of 50 should be getting 1 000 mg per day of calcium while those 50 and over need 1 200 mg per day.

10 The sarcoplasmic reticulum ceases to release calcium ions and immediately starts to resequester all the calcium ions that have been released 11 In the absence of calcium ions a change in the configuration of troponin and tropomyosin then blocks the action of the myosin molecule heads and contraction ceases.

Calcium absorption occurs by an active carrier dependent process and a passive paracellular process The active process is vitamin D dependent but the passive process is not When calcium intakes are low 25 OH D is converted to 1 25 OH 2 D which upregulates transcription of calcium transport proteins in the gut as described in Chapter 30

Your muscles contract through a process known as the sliding filament theory In this process myofilaments inside your muscle fibers grab hold of one another and slide to produce a muscular contraction However this is unachievable without the presence of calcium Actin and myosin are the myofilaments that produce a contraction.

When calcium is not binding to these receptors the cells release PTH which stimulates osteoclast proliferation and resorption of bone by osteoclasts This demineralization process releases calcium into the blood PTH promotes reabsorption of calcium from the urine by the kidneys so that the calcium returns to the blood.
