Final answer:
Neutrophils, eosinophils, basophils, lymphocytes, and monocytes are different types of leukocytes. Neutrophils are the most common and have a distinct lobed nucleus. Eosinophils have reddish-orange granules, while basophils have large dark blue to purple granules. Lymphocytes include B and T cells, and monocytes differentiate into macrophages and dendritic cells.
Step-by-step explanation:
Neutrophils: Neutrophils are the most common type of leukocyte and make up 50-70% of the total leukocyte count. They are larger than red blood cells, measuring 10-12 µm in diameter. Neutrophils have a distinct lobed nucleus, which may have two to five lobes, and their granules appear light lilac.
Eosinophils: Eosinophils have slightly larger granules that stain reddish-orange. They also have a nucleus with two to three lobes. Eosinophils play various roles in the immune response.
Basophils: Basophils have large granules that stain dark blue to purple. Their nucleus has two lobes. Basophils are involved in allergic reactions and inflammation.
Lymphocytes: Lymphocytes are agranulocytes and include B and T cells, which are responsible for the adaptive immune response.
Monocytes: Monocytes are also agranulocytes. They differentiate into macrophages and dendritic cells, which respond to infection or injury.
