vérrögképzdésért

Vérrögképződés, also known as thrombosis, is a vital physiological process that occurs when blood transitions from a liquid state to a gel-like or solid state. This transformation is crucial for hemostasis, the body's mechanism for stopping bleeding. When a blood vessel is injured, platelets, a type of blood cell, adhere to the site of injury and form a temporary plug. Simultaneously, a complex cascade of clotting factors, which are proteins in the blood, is activated. This cascade leads to the formation of fibrin, a fibrous protein that creates a mesh-like structure, reinforcing the platelet plug and forming a stable blood clot. This clot effectively seals the injured vessel, preventing excessive blood loss.

While essential for survival, uncontrolled or abnormal blood clot formation can lead to serious health problems. Thrombosis can occur within blood vessels when it is not needed, obstructing blood flow. If a clot forms in an artery, it can lead to a heart attack or stroke by blocking blood supply to the heart or brain, respectively. Clots forming in veins, known as venous thromboembolism, can cause deep vein thrombosis (DVT), potentially leading to pulmonary embolism if a piece of the clot breaks off and travels to the lungs. Various factors can predispose individuals to thrombosis, including immobility, certain genetic conditions, surgical procedures, and certain medical treatments.
