1. Describe the microscopic structure and Classification of leukocytes in the blood.


Leukocytes/white blood cells (WBCs)

WBCs are divided into monocytes, granulocytes, and lymphocytes. Monocytes stand out in the blood smear due to their size (15–20 μm). Monocytes typically have a kidney-shaped nucleus, and the cytoplasm appears pale grey under a light microscope.


The two main classification of leukocytes are granulocytes and mononuclear leukocytes (agranulocytes).





2. Describe the structure and function of RBC.


Red blood cells or erythrocytes are different from other cells of the body because they lack nucleus and most cell organelles.

 

     They have special cytoplasm that is rich in hemoglobin and therefore they are red in color.

 

     RBC or erythrocytes have special function in purification of toxic waste from our body, they carry oxygen and provide oxygen to other cells for cellular functions. They carry back carbon dioxide from cells; it is the toxic product of cellular respiration.


3. Definition of the Reticulocytes.

They are newly produced, relatively immature red blood cells.
