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.

Answer 2

Explanation:

The blood platelets are required for the process of blood clotting. Whenever there is an injury, to prevent the loss of blood it is necessary to form a clot. The vitamin K, clotting factors, calcium ions and the platelets are necessary agents for the formation of a blood clot. If there are no platelets, there will be no clot formation. This might result in haemorrhage in which there is continuous blood loss.
