How Does Blood Get To Giraffe’s Head?

The giraffe is mammal who lives in the savannahs in Africa and their Latin name is Giraffa camelopardalis. When we see a giraffe, we always wonder why they have so long necks. Their antecedents didn’t have long necks. Today’s giraffes developed long necks with evolution after trying to reach better fruits in the trees.

As they were elongating their necks they were also changing some other physiological characteristics.

The distance between the hearth and head of the giraffe is nearly two meters. The first issue here is the blood – how does it gets from the heart to the head? Giraffes changed their anatomies together with their necks. The earliest studies proved that the high blood pressure is twice greater than the high pressure of other mammals.

But the high blood pressure is not the only thing that gets the blood to the giraffe’s head and from it. When the giraffe drinks water the problem is opposite, because the head is under than heart.

Scientists have discovered that the heart of the giraffe is relatively small compared to their body. Although the heart is very small, it has very thick walls. The thick and strong walls allow the heart to pump blood with higher pressure and to long distances.

Also, the giraffe has very thick arteries and veins, which are very flexible, so the high pressure doesn’t have any negative effect on the animal.

Imagine how interesting has it been for the scientists to measure the blood pressure of a giraffe. One scientist stated that the experience was amazing in an interview.
