What cells comprise the Buffy coat?

The buffy coat is a thin layer of white blood cells and platelets that forms between the plasma and red blood cells when whole blood is centrifuged. It primarily contains leukocytes (white blood cells), including lymphocytes, monocytes, neutrophils, eosinophils, and basophils, as well as thrombocytes (platelets). This layer is crucial for immune response and clotting functions in the body.
