The blood pressure of a giraffe is the highest of all animals, reaching about 300 mm Hg in its systolic, or upper phase, and 200 mm Hg in its diastolic, or lower phase. The giraffe's blood pressure is higher than ours because the giraffe's heart has to pump blood up a neck seven feet long to reach his brain. The human brain, being only about 12 inches above the heart, is quite nicely served by a much lower blood pressure.

The giraffe is a big-hearted animal. On the average, the mass of a giraffe’s heart is about 40 kg. The giraffe needs a big heart with very thick muscular walls to pump sufficient blood a long distance, up the length of the neck to the brain. As a result, the giraffe has the highest blood pressure of any animal. The high blood pressure prevents giraffe from getting lightheaded. Giraffe's tall necks accompanies rapid head movements that could cause dizziness and loss of conscious if the blood circulation is disrupted. Similarly people rapidly shaking their head or pilots undergoing rapid maneuvering can suffer temporary unconsciousness from lack of sufficient blood.
