Blood clots are a potentially dangerous condition that occurs when blood coagulates, forming a semi-solid mass in blood vessels. There are many synonyms for blood clots, including thrombosis, coagulation, embolism, and thrombus. Thrombosis refers to the formation of blood clots in the veins or arteries, while coagulation is the process of blood clotting. Embolism occurs when a blood clot dislodges and travels to another part of the body, often causing blockages and tissue damage. Thrombus is a clot that forms within a blood vessel and is not dislodged. Regardless of the terminology used, blood clots can be prevented and treated, and it is important to seek medical attention if symptoms arise.
