works with platelets to help form scabs or clots works with platelets to help form scabs or clots
dried blood from scrapes or a cut, that clots (dried blood that quit bleeding) on the surface of your skin.
Platelets and fibers that they trap for scabs (external) or clots (internal).
Blood clots to stop the bleeding from any cut, so that blood loss if minimized. Scabs are the result of this clotting but also fulfill an important immune function. Without a skin barrier, bacteria and other pathogens are free to enter directly into the bloodstream. Scabs provide a barrier to this while skin heals.
because when you bleed the blood hardens and turns into scabs
you get scabs when you scratch and your blood hardens when you leave it untreated.
Blood is made up of four main parts. These are: Red blood cells. These are nuclei-less cells packed full of haemoglobin to carry oxygen around the body. White blood cells. These are the immune system of the body, and protect the body from any invading pathogens. Platelets. These are the cells that form scabs and clots when you get cut. Plasma. This is the liquid part of the blood, and makes up around 60% of the blood content.
Technically no. It is just a blood clot. It is dried up blood
Three maion cells are: -Red Blood Cells (carries CO2 away) -White Blood Cells (fights infections by making antibodies) -Platelets (Form scabs and blood clots) They are all suspended in the plasma which carries the Oxygen.
scabs are not "just" dried blood, they're formed by a chemical reaction, mainly of polimerized proteins and are quit water proof.
White blood cells that fight disease, red blood cells which carry oxygen, and platelets that form scabs.
As the clot starts to get hard and dries out, a scab forms. Scabs are usually crusty and dark red or brown. Their job is to protect the cut by keeping out germs and allowing the area underneath to heal. There isn't one organ system involved but at least three: cardiovascular system (blood), lymph (white blood cells eat bacteria, part of the immune system) and the skin (integumentary system) which acts as a Band-Aid.
