calcium as nutrient

Metal ions {calcium, nutrition} can be for bones, teeth, blood clotting, body-temperature control, nerves, muscles, and iron absorption.

sources

Calcium comes from dairy products, green vegetables, and egg yolks.

biology

High phosphate or high protein in diet increases calcium loss in urine. Citrate, oxalate, and phytate, in unleavened wheat and corn bread, precipitate calcium. Active transport in intestine absorbs calcium. Calcium flows across membranes during muscle contraction and at nerve synapses.

vitamin

Vitamin D puts calcium in bones.

hormones

Parathormone liberates calcium from bones. Calcitonin adds calcium to bones.

poison

Cadmium prevents calcium entry into bones {cadmium poisoning}.

disease

Osteoporosis bone loss involves calcium and protein loss.
