Answer:

Role of calcium

Almost all calcium is stored in bones and teeth, where it supports their structure and hardness. The body also needs calcium for muscles to move and for nerves to carry messages between the brain and every body part.

Role of Iron

Iron helps form and oxygenate our blood cells and haemoglobin. One of the most important functions of iron is in heme synthesis, which forms haemoglobin, a protein found in red blood cells. Haemoglobin's primary role is to transport oxygen from the lungs to body tissues to maintain basic life functions.
