The most common leukocytes in healthy blood are ordered based on their relative abundance in a typical differential white blood cell count. Neutrophils are the most prevalent type of white blood cell, making up approximately 50-70% of the total leukocyte count, which plays a key role in the immune response, particularly in responding to bacterial infections.

Following neutrophils, lymphocytes are the next most common, accounting for about 20-40% of white blood cells. They are vital for the adaptive immune system, including roles such as the production of antibodies and the coordination of immune responses.

Monocytes come next in the hierarchy, representing about 2-8% of total white blood cells. They are important for phagocytosis and can differentiate into macrophages and dendritic cells, contributing to both innate and adaptive immunity.

Eosinophils, which are involved in combating parasitic infections and in allergic responses, account for around 1-4% of the leukocytes in the blood.

Basophils, the least common type, make up less than 1% of the total white blood cell count and are involved in inflammatory reactions and allergies, releasing histamine and other mediators.

Thus, ordering these leukocytes from most
