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?

Solution – a. If more of Ca⁺ is in the extracellular fluid, then it will get accumulated into the bones under the influence of the hormone Thyrocalcitonin (TCT)

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