             The parathyroid gland's task is to measure, day and night, how much calcium
             there is in your blood and to maintain it at the ideal level. Whenever it determines
             that the level of calcium in your blood has fallen, it takes immediate precaution-
             ary measures.



             means of the parathormone it produces. If the amount of calcium in the
                                                         3
             blood falls, it immediately releases parathormone (Figure 20).
                  The parathyroid gland is a small piece of tissue. How does a piece of
             tissue consisting of cells identify the calcium atoms in the bloodstream
             flowing before it? How do cells with no eyes, ears or sensory organs iden-
             tify calcium atoms from among thousands of different substances in the
             blood—salt, glucose, fat, amino acids, proteins, hormones, enzymes, lactic
             acid, carbon dioxide, nitrogenous wastes, sodium, potassium, urea, uric
             acid, iron and bicarbonate? How does the cell recognize this one element,
             calcium, out of all these others? How does it know the ideal level of calcium
             there needs to be in the blood? By what consciousness does it measure that
             level? How does it decide whether there is too much or too little?
