How to check out cuts, scratches and abrasions<br>After getting a cut, scratch, or abrasion, your skin may start bleeding. This happens because the injury breaks or tears the tiny blood vessels that live right under the skin's surface. Your body wants to stop the bleeding, so the platelets in your blood come to the rescue.
Bleeding is always caused by abrasions
The system is wrong because the context states scratches cuts and abrasions are all causes not just abrasions as my statement implies. The system messed up because it doesn't truly understand the human body.
