Monocytes. Monocytes. Monocytes are the largest cells of the blood (averaging 15–18 μm in diameter), and they make up about 7 percent of the leukocytes. The nucleus is relatively big and tends to be indented or folded rather than multilobed.
What is the largest white cell?
monocyte This is a photo of a monocyte in a blood smear. These are the largest type of white blood cells, and can be up to 20µm in diameter. They have a large eccentrically placed nucleus, which is kidney bean shaped. They have abundant cytoplasm, and some fine pink/purple granules in cytoplasm.
Which is the most populous white blood cell?

What should WBC count be?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs.
Which leukocyte is second to least common?
Basophils are the least common leukocytes, typically comprising less than one percent of the total leukocyte count. They are slightly smaller than neutrophils and eosinophils at 8–10 µm in diameter.
What type of leukocyte can live for years?
memory cells Although one type of leukocyte called memory cells can survive for years, most erythrocytes, leukocytes, and platelets normally live only a few hours to a few weeks. Thus, the body must form new blood cells and platelets quickly and continuously.
Which is the smallest WBC?
Lymphocytes are agranular leukocytes which form from the lymphoid cell line within the bone marrow. They respond to viral infections and are the smallest leukocytes, with a diameter of 6-15µm.
Which is not a type of leukocyte?
Megakaryocytes (the cells that produce platelets) and erythrocytes (red blood cells) are not formally considered to be leukocytes, but arise from the common myeloid progenitor cells that produce the other cellular components of blood.
What kills white blood cells?
Cancer treatments such as chemotherapy or radiation therapy can destroy white blood cells and leave you at risk for infection.
What are the 5 white blood cells?
These broadest categories can be further divided into the five main types: neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
How many types of white blood cells are there?
The three major types of white blood cells are: Granulocytes. Monocytes. Lymphocytes.
What are the 3 things white blood cells do?
White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
What happens if white blood cells are high?
A high white blood cell count may indicate that the immune system is working to destroy an infection. It may also be a sign of physical or emotional stress. People with particular blood cancers may also have high white blood cells counts.
