Obviously, we want our blood to clot when we spring a leak. Three components must work together: Platelets The blood vessels themselves Protein Clotting factors If everything is working well, a clot forms in minutes.

• A healthy blood clot occurs when and where we want it.
•  At the site of a broken blood vessel, the point of injury.
•  A healthy clot stays put and does not cause a runaway clotting episode.
• A healthy clot knows when it's time to dissolve.
• A thrombus is a pathological clot.
• It develops in the fixed vascular system.
• It causes vascular narrowing or outright occlusion.
• It may embolize.

Wow, this is great. So, how do you measure this tiger?                                         Back
