Question

what would happen if platelets are absent in the blood​

Answer 1

The effect of the platelet response is to stop the bleeding and to form the site of the developing blood clot, or thrombus. If platelets are absent, this important defense reaction cannot occur, and protracted bleeding from small wounds (prolonged bleeding time) results.

• If there are no platelets, then the blood will not clot as platelets release blood clotting factor at the site of injury.
