A blood clot is an organized clump of hardened blood. Normal blood clotting helps stop blood loss, such as when you get a minor cut or scrape. However, a blood clot that forms inside a blood vessel (artery or vein) or in the heart is called a thrombus and is a serious medical condition. Blood clots can form in the superficial veins just below your skin, or they can form in the deeper, large veins (deep vein thrombosis).
