Giraffes have big hearts, weighing up to 26 pounds. When a giraffe lifts its head, blood vessels in the head direct almost all of the blood to flow to the brain, and not to other parts of the head such as their cheeks, tongue, or skin.
At the same time, the animal's thick skin and an unusual muscle in the jugular vein-veins don't normally have muscles-add pressure to the vein, which carries blood from the head back to the heart.
