If you accidentally cut it, you are cutting vegetables in the kitchen. Wash the wound with water and the bleeding will stop for a few minutes. The blood forms a clot and it helps stop the bleeding.


Have you ever wondered how blood really clots?

Human blood is composed of millions of cells, each serving a different function. Platelets in these cells — a type of cell that contains blood clots. There are various stages of blood clotting. Below is a brief description of what actually happens.


1. The blood vessel is cut or damaged. The wound encodes the platelets, which rush to the site of injury and begin the healing process. Platelets together form a "platelet plug" that closes the bleeding hole.

2. A chemical process called freezing factor (released from the liver) begins to stimulate proteins in the blood. These are called Factor V, Factor VII, Factor IX and Factor X (Roman Figures). Coagulation factors are involved in the formation of fibrin, a protein chain that helps provide strength and stability for platelet thrombosis.

3. Clotting is a chemical process, so something needs to be done to test it so that blood does not continue to clot. These include elements that include the “clotting police” and protein C, protein S, and similar proteins. They ensure that clots occur only at the site of injury and not elsewhere in the body.

Over time, blood clots harden and eventually burst and disappear. It is derived from an enzyme known as plasmin.

The entire freezing process takes about 2-6 minutes. Is it cool?

However, coagulation has a dark side.

Blood clotting is a protective process, but it can also lead to conditions such as strokes and heart attacks. For example, in a heart attack, narrow veins formed by atherosclerosis can cause restlessness that night and damage the lining of blood vessels. This causes platelets in the bloodstream to form a pile of platelets, leading to the formation of blood clots.

Blood clots block the blood vessels and drain the oxygenated blood myocardium. It causes heart attacks. A similar phenomenon occurs in the brain, leading to paralysis. It is not common in the legs and leads to "ischemic" limbs. This can lead to disaster and sometimes requires disconnection.

In such cases, antibodies such as aspirin, clopidogrel, and valfarin are required to prevent this process. They are life-saving treatments and maybe required in the long run.
