II. Match the mineral in brackets with its definition.

  1. An element over half of which is contained in hemoglobin in the red blood cells. It is an essential component in the transfer of oxygen in the body. Symbol: Fe.

  2. A metallic element that is necessary for the proper functioning of muscle and nervous tissue. Symbol: Mg.

  3. A mineral element that controls the volume of extracellular fluid in the body and maintains the acid-base balance. It also helps maintain electrical potentials in the nervous system and is thus necessary for the functioning of nerves and muscles. Symbol: Na.

  4. A metallic element that is an essential constituent of bones and teeth. Symbol: Ca.

  5. A mineral element that is the main base ion of intracellular fluid. It helps to maintain the electrical potential of the nervous system and is thus essential for the functioning of nerve and muscle. Symbol: K.

  6. An element required in small amounts for healthy growth and development. It is mostly concentrated in the thyroid gland which requires it for synthesizing thyroid hormones. Symbol: I.

  7. A trace element that is a cofactor of many enzymes. Symbol: Zn.

  8. A compound of fluorine whose ion incorporation in the enamel of teeth makes them more resistant to dental caries.

(Calcium, magnesium, potassium, sodium, fluoride, iodine, iron, zinc).
