The function of white blood cells and platelets in the buffy coat of a blood sample

The correct answer is: To fight infections and promote immunity

White blood cells (leukocytes) and platelets (thrombocytes) play vital roles in the immune system and blood clotting process, respectively. White blood cells are the body's defense mechanism against infections. They help identify and destroy pathogens, such as bacteria, viruses, and other harmful substances. Platelets, on the other hand, are responsible for forming blood clots to prevent excessive bleeding.

Having an adequate number of white blood cells and platelets is crucial for maintaining a healthy immune response and proper blood clotting ability. Any abnormalities in these components can lead to increased susceptibility to infections or potential bleeding disorders.
