How Do Blood Clots Form?


Chemical reactions grow the blood clot
o
Blood contains dissolved proteins, also
called clotting factors, which promote
blood clots. These signal and amplify
each other’s activity in massive numbers
at the site of bleeding.
o
This results in a chain reaction where the
end product is fibrin, the main protein in
forming blood clots.
o
The fibrin formed blood clot is tougher
and more durable than the platelet clump.
Anti-clotting processes halt the blood clot’s growth
o
The platelet plug forms
o
After a blood clot is formed, it must be
prevented from growing and spreading
through the body, where it could cause
damage.

The body breaks down the blood clot
o
As the damaged tissue heals,
the body breaks down the
blood clot and reabsorbs it.
o
An enzyme called plasmin
breaks down the tough fibrin
strands in a blood clot.
o
This breaking down is called
Thrombolysis or commonly
called clot busting.

Platelets clump together and
form a plug which reduces
bleeding
o
Anti-clotting proteins like antithrmbin
exist in a natural balance with clotting
factors.
Enzymes neutralize excess clotting
factors, which prevent them from
extending the blood clot farther than it
should go.

Sometimes a clot in a vein might be
detached from its original location and
travel to the lungs or heard where it
can become wedged, which prevents
blood flow. For lungs it is called
pulmonary embolism.
