The blood has platelet cells which circulate
around the body and help to clot the blood at
the time of injury. In the absence of platelets,
the process of clotting will be affected. Platelets
play the important role of coagulation of blood.
No blood coagulation would take place in the
absence of platelets. This would be a dangerous
situation in case of an injury, at it would result in
excessive blood loss and can even prove lethal
for the person.
