Thrombosis is the formation of a blood clot, known as a thrombus, within a blood vessel causing a partial or total obstruction; it prevents blood from flowing normally through the circulatory system. When the blood clot flows through the body, it can harm important organs such as the brain, heart, lungs, or leg arteries. When it blocks blood flow, serious health issues can arise, such as stroke, heart attack, or pulmonary embolism.
