Another form of calcium, calcium sulphate that is termed as gypsum have been found to be used in the construction of Great Egyptian Pyramid of Giza. Later in 1787, lime was considered as an oxide of a novel chemical element by Antoine Lavoisier.
Calcium Homeostasis - an overview | ScienceDirect Topics
Calcium homeostasis refers to the maintenance of a constant concentration of calcium ions in the extracellular fluid. It includes all of the processes that contribute to maintaining calcium at its “set point.” Because plasma [Ca 2+] rapidly equilibrates with the extracellular fluid, ECF [Ca 2+] is kept constant by keeping the plasma [Ca 2+] constant.
