What are the 6 types of white blood cells?
Types of white blood cells
- Monocytes. They have a longer lifespan than many white blood cells and help to break down bacteria.
- Lymphocytes. They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders.
- Neutrophils. They kill and digest bacteria and fungi.
- Basophils.
- Eosinophils.
How many types of white blood is there?
The three major types of white blood cells are: Granulocytes. Monocytes. Lymphocytes.
What are the 8 types of white blood cells?

What is the most common type of leukocyte?
Neutrophils are the commonest type of white blood cell found in a blood smear. They make up 60-70% of the total amount of white blood cells.
Why are there different types of white blood cells?
There are three different forms of granulocytes: Granulocytes are phagocytes, that is they are able to ingest foreign cells such as bacteria, viruses and other parasites. Granulocytes are so called because these cells have granules of enzymes which help to digest the invading microbes. Granulocytes account for about 60% of our white blood cells.
What are the different types of leukocytes in the body?
The total number of leukocytes and percentages of different leukocytes in the human peripheral blood are given in Table 4.1. There are different types of leukocytes: 1. Lymphocytes: Lymphocytes arise from the hematopoietic stem cells in the bone marrow. The normal adult human has about trillion (10 12) lymphocytes.
Where are white blood cells found in the body?
Leukocytes are made in the bone marrow from multipotent cells called hematopoietic stem cells. Leukocytes exist in all parts of the body, including the connective tissue, lymph system, and the bloodstream. There are five different types of white blood cells, each of which has a different funtions in the immune system.
Why are granulocytes called white blood cells?
Granulocytes are so called because these cells have granules of enzymes which help to digest the invading microbes. Granulocytes account for about 60% of our white blood cells. Neutrophils are by far the most prevalent of these cells. Each neutrophil cell can ingest up to between around 5 and 20 bacteria in its lifetime.
