Answer 2

Calcium

Step-by-step explanation:

Calcium is needed in our body to make bones (skeletal system) and teeth strong. Apart from making bones and teeth strong, it is required in other body functions such as:

Enabling blood to clot

Helping in muscle contraction

Helping heart muscle in maintaining normal heart beat

About 99% of calcium present in the body is stored in bones. Calcium is stored in bones in the form of calcium phosphate.

Bones continuously replace old calcium with new one. Calcium is not produced in our body. It comes from daily diet, therefore, it essential to take calcium rich diet.
