platelets
the color of platelets is purple. excessive amount of platelets in the blood(thrombocytopenia) may be manifested as purpura(purplish discoloration of the skin)
By forming a clot
Fibrinagen works with platelets (a componenet of blood) in order to help repair skin. The fibrinagen and platelets work together to sort of "sew" your skin back together.
Platelets
No. They are cells that help heal wounds on your skin. Blood vessels are arteries and veins.
These cells are called platelets. A normal count will assist in clotting cuts in the skin or tissue, a high count may cause blood clots elsewhere in the body and a low count can cause a cut to not clot, causing the victim to loose to much blood.
Platelets are cell fragments which are an important part of blood clotting. Similarly to red blood cells, they don't have a nucleus, but they are a lot smaller than red blood cells. When there are too few platelets, wounds don't close as well and you bleed more. Conversely, when there are too many, your blood clots too easily and blood clots might form without there being a wound - leading to thrombosis. However, the range of platelet counts that are healthy is very large, unlike for other blood cells. If you're on the lower end, somebody with five times as many platelets as you might still be perfectly healthy. How they work: When a blood vessel is injured, blood comes into contact with the protein mesh underneath the vessel wall. This mesh contains collagen. Blood contains platelets, but also a protein called Von Willebrand Factor (VWF), which sticks to collagen. Once it is stuck down, VWF itself becomes sticky for platelets which are also in the blood. This way, VWF becomes like glue stripts for platelets to stick onto an injury. This causes platelets to activate and stick to each other, forming a plug over the injury. There are more details to what platelets do, but this is their main function.
Protects cuts and gaps in the skin. I would ask your doctor about this.
Thrombocytes (Platelets) ~ 54.3%Erythrocytes (Red Blood Cells) ~ 45%Leukocytes (White Blood Cells) ~ 0.7%Red blood cells carry dissolved substances around the body, eg. Oxygen.White blood cells are part of the immune system, defending against unknown materials.Platelets help your blood clot if your skin ruptures, to stop it from bleeding further.
Platelets contain clotting factors that cause them to stick together, which stops bleeding from an opened blood vessel by solidifying the blood (hemostasis). Platelets also carry the growth factors (PDGF) that stimulate the growth of new blood vessels, which is called angiogenesis.
NO, herpes doesn't spread through blood only by skin contact with the sores.
