the blood
Blood is the fluid that circulates in the blood vessels, and has several components each with certain functions, and these components platelets, which form the most important part of the formation of clot, or thrombus, but in fact the coagulation that occurs to the blood is necessary to preserve human life, it is Works to repair the walls of the blood vessels, and this is evident when exposed to a wound, or during surgery, without them will be kept blood vessels in permanent bleeding.
Causes of stroke
Stroke occurs naturally and even useful when the blood vessels are damaged, but sometimes cause multiple problems, depending on their location. The causes of the stroke also vary according to their location. The blood vessels are divided into arteries; they carry the clean blood carrying food and oxygen to the cells, ; Which carry blood that carries cell waste, which is as follows:
- The clot of veins: This type of stroke affects people whose lives have a nature of idle, and lack of movement, do not muscle pressure enough in the veins, which slow the return of blood to the heart, and form small thrombocytes that grow and grow over time, and is similar to this type of clots by the river Light flow, it allows the growth of algae and plants, which narrowed its course, unlike the river raging that pulls everything with him.
- This type of stroke occurs because of the increase in the level of fat in the blood, which is known as low-density lipids, or harmful cholesterol, which makes them deposited in different places of the arteries, which is narrowing, and thus blockage in whole or in part, A diet rich in fat, and lack of exercise.
- Heart clotting: Thrombosis can occur in one part of the heart, either in the atria or in the ventricles. This is due to weakness or malfunction of the heart, so it is not able to pump blood properly.
- There are reasons to increase the risk of stroke, such as smoking, diabetes, and sitting for long periods without mobility such as when traveling, or when breaking bones, the block prevents the movement of the injured part, and genetic defect works to increase the speed of coagulation, Of the lower body, increasing the chance of stroke in the legs, pelvis.
The risk of clots varies according to their location. It can be in place and does not have a clear effect, such as if the blood vessel is wide, but it can move. The heart reacts with the blood to reach narrow or vital places such as the pulmonary artery. In the life of the injured person.
