Hemophilia is a condition in which blood does not clot naturally, and a person with hemophilia could bleed to death if injured. a hemophiliac must receive regular injections of what blood part to stay alive?

As we know our blood has four main components which are plasma, red blood cells, white blood cells and platelets. That is why a hemophiliac must receive regular injections of platelets to stay alive. This is done by injecting into their bloodstream human plasma which contains many proteins, glucose, clotting factors, electrolytes, hormones, and carbon dioxide.

I hope it helps, Regards.
