Biologically

Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.

Maintaining extracellular calcium concentrations within a narrow
range is critical for the survival of most vertebrates. PTH, together
with vitamin D, responds to hypocalcemia to increase extracellular calcium levels, by acting on bone, kidney and intestine. The recent introduction of PTH as a major therapeutic agent in osteoporosis has directed
renewed interest in this important hormone and in the physiology of the
parathyroid gland. The parathyroid is unique in that low serum calcium
stimulates PTH secretion. As hypocalcemia persists, there is also an increase
in PTH synthesis. Chronic hypocalcemia leads to hypertrophy and hyperplasia of the parathyroid gland together with increased production of the
hormone. Phosphate is also a key modulator of PTH secretion, gene expression and parathyroid cell proliferation.
