What is the Circle Willise?

Circle Willis is a ring or a circle of arteries located on the base of the brain. This is also known several other names, most often the brain arterial circle and arterial circle Willis. This part of the brain was first discovered by English doctor Thomas Willis in the 17th century. The circle is important to itself and the brain, because the way the artery is distributed provides the form of a backup in case any of them is defended. If one artery is narrowed or blocked, the blood flow from the other arteries in the circle will most often be enough to maintain the necessary flow to the brain and prevent damage. It was found that the circle provides the necessary blood and fuel for all thought processes and even physical processes in the brain. This very effective clump of arteries essentially provides all the blood that comes and leaves the brain that needs survival and operation.

While it was found that the formula of the loop in which the lay artery of the lains creates for pBlood rush and significantly reduce the risk of blood pressure changes in the brain, is not completely infallible. Some blockages caused by debris or blood clots or even bleeding are still able to cause devastating effects such as strokes. Sometimes death may occur if these blockages become large enough or occur in the wrong place.

Many assume that the Willis circle can be properly represented by diagrams displayed in books that have a much more complex shape than a simple circle. But the truth is that about two-thirds of the human population do not have a complete "circle"-most of them are missing. No specific evidence supports that a person with an incomplete Wilis circle is exposed to a greater risk of blows.

While the Willis Circle does not have to be studied as closely as the higher function of the brain and thinking, it is generally accepted as the most important part of the brain. Without the Willis circle, the blood would not take the brain properly and its function would not be impossible. It is often said that life itself would not be possible or possible without this aliveOpine important structure maintained blood regularly.
