  • RBCs/ Erythrocytes : The red blood cells are responsible for carrying oxygen to all cells and tissues. They are biconcave in shape. They have a central pallor and the hemoglobin is located along the circumference of the cells. They are around 6.2-8.2 microns in diameter and 2-2.5 microns thickness in the thickest part. They are among the smallest cells in the human body.
  • WBCs/Leukocytes:They perform a variety of functions but immunity is the most significant one. They are larger than RBCs. They are of the following types: neutrophils, eosinophils, basophils lymphocytes and monocytes. The first three are granular and thus called granulocytes while the rest two are agranulocytes.
  • Platelets: They are also known as thrombocytes. They are discoid and biconvex with their greatest diameter being 2-3 micrometers. They are responsible for blood clotting.
  • Blood proteins: They are also known as plasma proteins. All of them are synthesised in the liver except gamma globulins. They transport lipids, hormones, vitamins and minerals and also maintain the plasma oncotic pressure.
