Select one: True False

The statement "The 'buffy coat' layer of the blood is made up of thrombocytes (platelets) and leukocytes (WBC)" is

True.

The buffy coat is the portion of a blood sample that lies between the plasma and erythrocytes layer. It is mainly composed of white blood cells and platelets. The white to yellowish colored buffy coat varies in thickness based on the number of white blood cells and platelets present in the sample.

White blood cells found in the buffy coat include lymphocytes, monocytes, and granulocytes. Lymphocytes are crucial for antibody production in the immune system, while monocytes play a role in engulfing and breaking down harmful bacteria. Granulocytes can be subdivided into neutrophils, eosinophils, and basophils, each playing a specific role in the immune response.

Platelets, also known as thrombocytes, are colorless cell fragments responsible for clot formation and stopping bleeding when needed in the body. They are not red or white blood cells but serve a critical function in maintaining hemostasis.
