Brian McGrory Blood Clots Arteries are blood vessels that carry blood away from the heart to body tissues and organs.
Veins are blood vessels through which blood travels from all parts of the body back to the heart.
A blood clot is a jelly-like mass of thickened blood. The body normally forms a blood clot to stop bleeding. After hip surgery there will be a blood clot near the new hip joint. This is normal, and not dangerous. If a blood clot develops inside a vein, however, it can block the normal flow of blood and cause temporary and long-term problems.
