All about Glóbulo Blanco (Leucocito)
|Description||White blood cells are your body’s warriors, fighting against infection and disease. They use the blood stream to get to the places where they need to fight harmful substances like bacteria and viruses. Bone marrow is the factory for white blood cells, which are then stored in the blood and lymphatic tissues. This is a fun gift for medical professionals, students, and teachers!|
Monocytes: break down bacteria and have a long lifespan.
The name white blood cell comes from the appearance of the cells after centrifugation. The name leukocyte comes from the Greek: Leuko=white, Cyte=cell.
Lymphocytes: make antibodies (hyperlink to antibody page) that help the immune system to protect against harm.
Neutrophils: attack bacteria and fungi, and are the most plentiful of all the white blood cells. They are the first line of defense for an infection.
Blasophils: release chemicals that inform the immune system of harmful substances. They are involved in allergic reactions.
Eosinophils: attack and destroy parasites and cancer cells and help in allergic reactions.
|Actual Size||Approx. 12 micrometers, which would be less than an eighth of the thickness of a sheet of paper.|
|Quantity||On average: 7,000 per microliter of blood, which translates to over 25 trillion white blood cells in the body. They make up 1% of the blood.|
|History||1834: Gabriel Andral and William Addison were both first to view and describe leukocytes.
1865: Max Johann Sigismund Schultze gave the first description of neutrophils and different types of leukocytes.
Paul Ehrlich contributed a lot to the research of immune cells. He was the first to identify them, and he showed that the eosinophil leukocytes were mainly produced in bone marrow.
|Fascinating Facts||Osmosis Jones: This 2001 movie with Bill Murray depicts a white blood cell protecting its human from a virus.
Blood Wars: Kathy High has produced an art-science installation that puts two different people’s white blood cells together to compete.
