Exchange of calcium between bone and extracellular fluid takes place under the influence of certain hormones

a. What will happen if more of Ca++ is in extracellular fluid?


b. What will happen if very less amount of Ca++ is in the extracellular fluid?

b. If very less amount of Ca++ is in the extracellular fluid thin bone resorption would occur due to the Parathyroid hormone.
