Q- Blood proteins are incapable of blood clotting inside the blood vessels but from the blood clot at the injury. How is it possible?
Answer- We all know that blood proteins are incapable of blood clotting inside the blood vessels. Still the blood get clotted when any injury takes place in blood vessels that is because of the presence of blood platelets in the blood that forms a net like structure at the part where injury takes place and this net clots the blood and prevent the flow of blood out of the body. In this way blood platelets are responsible for blood clotting in the body.
