      Blood doesn’t clot inside the blood vessel because the chemical (plasma proteins) which causes the blood to clot in the cut area gets activated only when it comes in contact with air (oxygen actually) to form the clotting substance.
      therefore when u get internal bleeding, its dangerous and often leads to death because likely coming into contact with oxygen air is lower than when u cut ur skin on the surfae; internal bleeding is also difficult to manage
      kind regards
