Explain the concentration of platelets in human blood.
(N/A) Platelets,also known as thrombocytes,are cell fragments produced from megakaryocytes in the bone marrow.
In a healthy human adult,the blood contains approximately $150,000$ to $350,000$ platelets per $mm^3$ of blood.
These cells play a crucial role in the process of blood coagulation (clotting) to prevent excessive blood loss during an injury.
