There can be a variety of reason for a cut to not heal properly. When there is an open wound that does not heal is is referred to as an ulcer. Whatever the cause may be, the best thing is to go see a doctor right away. If there is any kind of bacterial infection it can be very serious.

∙ 14y agoA scab is produced by platelets and it stops the bacteria getting through the body which saves work for your white blood cells.
The scab gets hard and makes a ''barrier'' to stop germs getting in your body.

∙ 9y agoScabs patch up holes in the skin. Certain cells in our bloodstream recognize when our skin has been broken. These cells, called platelets, start patching the break in the skin and call in other blood components to help complete the process. They do an amazing job. Don't make your platelets work overtime by picking your scabs!

What do white blood cells do in a scab?
Scab is the rusty brown, dry crust that forms over any injured surface on skin, within 24hrs of injury.Whenever our skin is injured due to any cut or abrasion, it starts bleeding due to blood flowing from the severed vessels. This blood containing platelets, fibrin and blood cells, soon clots, to prevent further blood loss. The outer surface of this blood clot, that is exposed to air, dries up (dehydrates) to form a rusty brown crust, called a scab, which cover the underlying healing tissues like a cap.The purpose of a scab is:to prevent further dehydration of the healing skin underneath,to prevent it from infections,to prevent any entry of contaminants from the external environment.Scabs generally remain firmly in place until the skin underneath has been repaired and new skin cells have appeared, after which it naturally falls off.

When you bleed red blood cells form a scab?
Red Blood Cells (RBC) do not "form a scab", they are merely trapped in the scab during blood coagulation. Platelets, carried in the blood serum form the scab by sticking to the endothelium (inside) of the blood vessel forming a plug to end bleeding. Clotting proteins than begin to condense and form the hard scab. Human RBC do not have DNA and therefore cannot act in response to external stimuli like a cut.
