And when the team contracted the bottom of the jugular vein, they found a dramatic increase in blood pressure. They suggest that by constricting the jugular vein at this point, the giraffe can maintain sufficient blood pressure to prevent fainting when raising its head after drinking alcohol. January. 2006г. Therefore, giraffes crouch down, drink, and look around before taking turns staring at each other. It has an internal structure that prevents large amounts of blood from flowing into the head when drinking the ground or water. Fortunately for giraffes, nature offers a complex pressure regulation system that controls blood flow. Their brains have blood vessels that connect to the complex valves of large neck veins and blood sponges. These are specifically aimed at lowering blood pressure before it enters the brain. A series of special one-way valves in the neck regulate blood flow, and at the base of the brain there is a special net of elastic blood vessels. Without these valves and elastic blood vessels, the blood pressure in the giraffe's head becomes huge as it bends, enough to damage the brain.

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 damage to the brain. However, if it is difficult to get all the blood uphill so far, you will have high blood pressure.
How does a giraffe control blood pressure?
Fortunately for Kirin, nature has provided Kirin with a complex pressure regulation system that controls blood flow. Their brains have blood vessels that connect to the complex valves of large neck veins and blood sponges. These are specifically aimed at lowering blood pressure before it enters the brain.
Why does a giraffe have such a 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.
What if the giraffe has elastic blood vessels?
Their brains have elastic blood vessels that connect to the check valves in the neck to prevent the head from swelling when the head bends. If these things weren't present, the giraffe couldn't survive. On their paws, the blood vessels are under so much pressure that no other animal can handle it.
How does a giraffe maintain blood pressure?
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 allows blood to return to the heart instead of collecting in the legs. 2017
How does a giraffe overcome gravity as blood circulates in the head?
A strong elastic ligament structure in the neck reduces muscle effort Required to support the head and neck. The arteries above the heart are muscular and elastic, pumping blood to the brain against gravity.
How does a giraffe avoid a head rush?
It takes a strong heart to pump blood to the head. Beat up to 170 times per minute. It's twice as fast as we do. (Gentle music) This huge blood pressure is the highest in mammals and should plunge a bad head into a drinking giraffe, but instead a clever valve system regulates blood flow to the brain. increase.
How do giraffes get dizzy?
If your blood pressure drops too low, your brain will not get enough blood and you may faint. Due to its long neck, giraffes spend a lot of time moving their heads from bottom to top. As a result, giraffes spend a lot of time moving their heads from bottom to top. Therefore, we need a way to keep the blood flowing to the brain so that the head does not get messed up. 2006
