Question

Quizplus · Accepted Answer

Fast calcium exchange refers to the rapid movement of calcium ions between bone and extracellular fluid. During this process, the source of calcium is the bone fluid, which is a fluid that surrounds the bone cells (osteocytes) and contains dissolved minerals, including calcium. Blood plasma and liver calcium stores are not involved in fast calcium exchange, and while dissolution of bone can release calcium into the bone fluid, it is not the source of calcium during this specific process.
