Why is a giraffes blood pressure so high?
Abstract. The giraffe is unique as its head is 2500-3000 millimeters above its heart, thus the giraffe’s heart must pump hard enough to overcome the huge hydrostatic pressure generated by the tall column of blood in its neck in order to provide its head with sufficient nutrients and oxygen.
Are giraffes friendly?
Humans and giraffes have a different type of relationship than that of many other animals. Giraffes have never served a significant purpose for people, yet they haven’t been seen as a threat either. … They love the gentleness as well as the fact that they are so different from other animals out there.

Next, the giraffe clenches its lips, relaxes the epiglottis, and pumps its jaw so that the captured water is pushed into the esophagus.
Do giraffes get concussions?
Giraffes also use their long, powerful necks to assert their dominance. … Unsurprisingly, giraffes have thick skulls to protect against concussions from such impacts.
