Hemodynamics and Drinking in the Giraffe
Central blood pressure decreased when the head was lowered, but drinking per se caused a surprising rise in blood pressure to pre-drinking levels. This rise in blood pressure is likely due to the transfer of esophageal water boli acting on the jugular veins. The cephalic capillaries are protected by a strong myogenic response and sympathetic innervation.
