And to compensate for high blood pressure, blood vessels contract and dilate to maintain volume. Giraffes wear natural compression socks on the neck and legs in the form of very tight skin. This causes blood to return to the heart instead of collecting in the legs. 26th. 2017 г. Giraffes are tall in the sky, and in adults, they rise about 6 meters above the ground, resulting in high blood pressure. This is a long way for the heart to pump blood against gravity. In order for the blood pressure in the brain to be 110/70 (almost normal in large mammals), the giraffe needs to have the blood pressure in the heart about 220/180. Therefore, giraffes look around before crouching, drinking or taking turns. Looking at each other. Giraffes have an internal structure that prevents large amounts of blood from flowing into the head when drinking ground or water, and wears natural compression socks with a very tight skin shape on the neck and legs. increase. This allows blood to return to the heart instead of collecting in the legs. Studies show that giraffes, unlike other similar animals, have a small, supercharged heart. A two-foot-long heart weighs about 12 kg and is extremely powerful at pumping blood to its long neck and legs. In addition, the heart has evolved to have a small radius and a thick muscular wall, giving it high strength.

Why do giraffes have high blood pressure?
Giraffes have very high blood pressure, so for adults, the height of the head is about 6 m (19 feet) above the ground. This is a long and long way for the heart to pump blood against gravity. Maintaining a blood pressure of 110/70 in the brain is almost normal in large mammals, but giraffes require a blood pressure of about 220/180 in the heart.
Why do giraffes bow their heads and drink water?
When a giraffe drinks water by lowering or lowering his head, not only does gravity decrease, but the opposite is true. Otherwise, the blood pumped towards the brain at high pressure can lead to brain damage. However, if it is difficult to get all the blood uphill so far, you will have high blood pressure.
Why do giraffes wear compression socks around their necks?
A heavy 25-pound heart maintains the strong pulsations needed to drain blood into the brain. And to compensate for high blood pressure, blood vessels contract and dilate to maintain volume. Giraffes wear natural compression socks on the neck and legs in the form of very tight skin.
How strong is the giraffe's heart?
First of all, the giraffe's heart is one of the most powerful of all mammals. Studies show that giraffes, unlike other similar animals, have a small, supercharged heart. A two-foot-long heart weighs about 12 kg and is extremely powerful at pumping blood to its long neck and legs.
Why does a giraffe have high blood pressure?
Kirin has a high head and, in the case of an adult, rises about 6 m (19 feet) above the ground, resulting in high blood pressure. This is a long and long way for the heart to pump blood against gravity. 2021
How does the giraffe's circulatory system work?
Instead, the giraffe's heart is relatively small (compared to the size of the animal), and its power comes from a very strong beat as a result of the incredibly thick wall of the left ventricle. .. The right ventricle pumps blood to the lungs in a short distance, and the muscle is about 1 cm thick.
What happens to the blood pressure in the giraffe's neck when I bend down and drink it?
When you drink with your head down, a special valve on your neck counteracts the explosive effects of gravity and blocks blood returning to your skull. Pressure suits built into very long legs, on the other hand, prevent fluid and blood from collecting in your feet.
What is the blood pressure of a giraffe?
In fact, according to zoologists, the blood pressure of an adult giraffe can reach 300/180 millimeters. This is about twice that of an adult. But it's close to their hearts.
