How does blood clot?
With the help of glue.
Not at all.
Our blood consists of red blood cells, white blood cells, platelets, clotting factors, etc.
Suspended in a liquid plasma.
Hey.
I too have a plasma, look.
Please listen.
Usually, when a blood vessel gets ruptured and we bleed, our blood begins to form a clot.
First, the platelets start sticking to the broken vessel and each other.
Thus forming a loose plug.
But this plug is not enough to stop bleeding.
Hence,
The clotting factors take part in a complex chain of chemical reactions and create fibrin strands.
These strands criss-cross one another and create a mesh that tightly holds the loose plug together.
Makes it strong.
Red blood cells and white blood cells also get trapped in the mesh.
Thus creating a blood clot that completely stops bleeding.
