Parathyroid glands
identify calcium
from among the Thyroid gland
millions of mole-
cules in the blood
and take the appro-
priate precaution-
ary measures to Parathyroid gland
maintain the ideal
level of calcium in
the blood.

Remember that these parathyroid cells have no intelligence or con-
sciousness, and are only 1% of a millimeter in size. That they are able to
successfully measure the level of calcium in our body on our behalf is just
one of the proofs of the creation of the Omniscient and Almighty God.
If, as a result of their measurements, the parathyroid cells determine
that the calcium level has fallen, they immediately secrete parathormone.
But how is the level of parathormone raised, and how is this tiny molecule
able to locate stored calcium? Parathormone finds sources of calcium to re-
plenish the blood from three different sources, each of which requires a so-
phisticated biological knowledge:
1. There are high levels of calcium in the bones. Parathormone bor-
rows some calcium from the bones. The bones, under normal conditions,
are reluctant to release the calcium. When they encounter the parathor-

mone formula, however, they naturally release a small quantity of calcium
(Figure 20).
2. A certain quantity of the calcium in the blood is expelled from the
body through urine. This calcium needs to be re-combined with the blood
once again. To accomplish this, the kidney cells need to capture the calcium
molecules in urine and to return them to the bloodstream.
This time, parathormone issues this command to the kidney cells. The
cells obey the command and extract the calcium molecules (Figure 21).
3. New sources of calcium enter the body through the food we eat.
That calcium in is mixed with the blood in the small intestine. However, in
