The giraffe's heart weighs an average of 11 kilograms and is made up of two halves, right and left (like all mammals), each of which is responsible. Studies show that the giraffe's heart is supercharged and the heart is different. Than other similar animals. 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 power. Giraffes have high blood pressure in adults because they have a high head about 6 meters above the ground. , A long way for the heart to pump blood against gravity. To get the blood pressure in the brain to 110/70, it is almost normal for large mammals, but the blood pressure in the giraffe's heart should be about 220/180.
safari-center.com Изображение: safari -center.com ZOO-ology: The giraffe's heart is 2 feet and weighs 25 pounds. Giraffes have a larger heart that can pump 16 gallons per minute. This helps to transfer blood throughout the body of long-necked and long-legged mammals.
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.
Is the giraffe hypertensive?
For Kirin, blood circulation is a tall order. The heavy 25-pound heart maintains the powerful beats needed to drain blood into the brain. And to compensate for high blood pressure, blood vessels contract and dilate to maintain volume.
Why are giraffes so long? Neck and long legs?
When asked why such a long neck or leg is unknown, I answered the question of how blood circulates. There is also a myth that giraffes often suffer from high blood pressure caused by constant uphill and downhill blood rise, as the distance between the heart and brain and to the legs is exactly 6 feet.
How thick is the giraffe's left ventricle?
Africa Geographic estimates that the left ventricle can be up to 7 centimeters thick. The giraffe's left ventricle is not the only one helping to fight gravity. The heart beats 40-90 times a minute during rest and up to 170 times a minute during running. More notably, the giraffe's blood pressure is very high.
