We all know that the giraffe is a cute animal characterized by its long neck, but did you know about its suffering with gravity? Of course not, that is why in this post we will talk about the suffering of the giraffe with The gravity, and what did the person benefit from this phenomenon?
The giraffet and the Gravity
Gravity is a giraffe's staunch enemy, with its presence it is not easy for blood to cross the neck of 2 meters to reach the brain, so the giraffe needs a supercharged heart hitting hard enough to overcome this great downward pressure caused by gravity to blood.
Giraffe heart
The Giraffe face the gravity
-The adult giraffe has a heart with incredible capabilities, weighing more than 11 kg (20 times the weight of a lion's heart - 31 times the weight of a human heart) with a length of 60 cm, and a speed of 180 beats per minute - It produces thrust / pressure of blood twice twice that of mammals, Supplier With walls thickness of 7.5 cm to avoid tearing or bursting; If a heart is transplanted like this, the human body (60 seconds) will suffer a stroke before the vessels of the brain, eyes and kidneys explode - and will suffer from sterility as collateral damage.
Despite these mighty capabilities, the giraffe suffers from a weak heart, so it needs a way to increase blood pressure and keep it flowing to the brain, so the giraffe eats from short trees to fill its head with blood and then rises every two seconds at least, before raising its head to the sky comes the role of the neck skin Feet are so thick and taut as socks to force the blood back into the body, that even the anti-g-suit worn by the pilot is designed on this principle.
