Among these different types of WBCs, neutrophils are the most abundant and make 60-70% of the total WBCs present in the blood. Basophils are the least abundant WBCs and make only 0.5-1.0% of it. Eosinophils and monocytes make 2-4% and 3-8% of the total WBCs respectively.
What is the smallest blood cell?
Platelets are the smallest of the three major types of blood cells. Platelets are only about 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume.

Monocytes are a type of white blood cell. They are produced in the bone marrow and then enter the bloodstream. They fight certain infections and help other white blood cells remove dead or damaged cells and fight cancer cells.
What cells are granulocytes?
Neutrophils, eosinophils, and basophils are granulocytes. A granulocyte is a type of white blood cell. Also called granular leukocyte, PMN, and polymorphonuclear leukocyte.What do basophils do?
Basophils play a part in “immune surveillance”. This means they have the ability to help detect and destroy some early cancer cells. Another important function of basophils is that they release the histamine in their granules during an allergic reaction or asthma attack. Allergic reactions.

All of the formed elements of blood originate from this specific type of cell. … Lymphoid stem cells give rise to a class of leukocytes known as lymphocytes, which include the various T cells, B cells, and natural killer (NK) cells, all of which function in immunity.Which formed element is not a true cell?
The formed elements include erythrocytes and leukocytes, which are cells (although mature erythrocytes do not have a nucleus); however, the formed elements also include platelets, which are not true cells but cell fragments.
