How Does Blood Clot?
Blood has a seemingly impossible job: It must flow continuously and smoothly throughout your body for an entire lifetime, but quickly shut off to prevent spills when you get a cut or injury.It acomplishes this by a series of interaction between different factors.
The Animations presented here are further divided into two types
Simplified for those who are interested in an general overview and
Detail for thos who are interested in more detail.
In general the whole process can be divided into the below stages
Formation of Platelets plug:
Formation of Platelets plug: Tiny bits in your blood called platelets get "turned on" by triggers released when a blood vessel is damaged. They stick to the walls in the area and each other, changing shape to form a plug that fills in the broken part to stop blood from leaking out. When activated, platelets also release chemicals to attract more platelets and other cells, and to set off the next step.
Formation of clot:
Proteins in your blood called clotting factors signal each other to cause a rapid chain reaction. It ends with a dissolved substance in your blood turning into long strands of fibrin. These get tangled up with the platelets in the plug to create a net that traps even more platelets and cells. The clot becomes much tougher and more durable. . Reactions stop its growth. Other proteins offset extra clotting factor proteins, so the clot does not spread farther than it needs to.
Resolution of Clot:
As the damaged tissue heals, you do not need the clot anymore. Your body slowly breaks the clot down. The tough fibrin strands dissolve, and your blood takes back the platelets and cells of the clot.
Other Factors Involved in Clotting process:
These are some factors that play an important role in clot formation in more detail.
