Editing Blood Clotting (section)

== Why This Works ==

Wound healing is an important property of our bodies. When the skin is injured and cut, there are three stages to the recovery process we call ''Hemostasis''. The first stage is when the platelets in the blood start to stick together at the injury site. ''Platelets'' are flat cells in the blood which, when activated, will stick to each other at the injury site, and release a chemical response to encourage other platelets to stick there as well. This stage is when you first see that a cut has stopped bleeding, and there is a semi-clear blob on the cut. If you poke this, however, then the cut will reopen and continue to bleed, since the platelets are only a short term fix. The second stage is when fibrin starts to collect at the injury site. ''Fibrin'' is a protein in the blood which, when activated, creates a strong membrane over the injury site. This is when a cut has a scab on it, and scabs are much harder to break. The third stage is when the body does the repairs at the location by removing the dead cells and replacing them with live cells. During this part the fibrin and platelets will be re-dissolved into the blood, the skin will grow back, and the cut will be healed!
