By narrowing the blood vessels leading to the liver and skin, adrenaline prevents
blood from flowing to organs where it will not be needed, for the time being.

blood loss in the event of injury is reduced to a minimum. The pallor ap-
pearance of someone who is terrified or extremely excited arises from less
blood being pumped to the skin at that moment. 6
The vessels leading to the heart or brain are never narrowed by mis-
take, and those leading to the liver or skin are never expanded. The adren-
aline molecule does its job very well. The diameters of the hundreds of
blood vessels in the body and the amount of blood transmitted by these,
and to where, are all regulated by a hormone, in quantities too small to be
detected with ordinary senses.
Adrenaline has a different significance for every organ it encounters.
When going to the blood vessels, it expands them, and when it goes to the
heart, it accelerates the contraction of the muscle cells there. In this way, the
heart beats faster, and the muscles obtain the extra circulation they need to
produce extra strength (Figure 34).
When the adrenaline molecule reaches muscle cells, it enables them to
