Blood Clot Prevention
What is a Blood Clot?
A normal blood clot consists of a "clump" of blood-born particles that have become "stuck" together inside a blood vessel; this usually occurs at the site of a blood vessel injury and is part of the normal healing process. However, clotting also can occur in areas where blood flow is slow or stagnant, such as in a blood vessel occluded, or obstructed, by atherosclerotic plaque. A blood clot that develops in a blood vessel or the heart and remains there is called a thrombus, while a blood clot that has broken loose and floats freely through the circulatory system is called an embolus.
Blood clots are made up of:
Platelets: Small fragments of larger cells called megakaryocytes, platelets circulate through the blood and carry important substances such as proteins and other cellular signaling molecules. A platelet has a lifespan of about 7–10 days.
Red blood cells: The most common type of blood cell, red blood cells transport oxygen from the lungs and distribute it to all the tissues of the body.
White blood cells: The cells of the immune system, white blood cells originate in the bone marrow as stem cells that differentiate into various types of immune cells.
Fibrin: A web-like proteinaceous gel, fibrin binds the other components of the clot together.
