キリンの高血圧の秘密?
Giraffes are the tallest animals on land, with necks that can be about 1.8 meters long. To pump blood up such a long neck, their hearts are very strong and have high blood pressure. In fact, giraffes have the highest blood pressure among animals, reaching about 280/180 mmHg. This is about twice as high as a typical human blood pressure.
