Life span of human white blood corpuscles is

White blood corpuscles, also known as leukocytes, are responsible for protecting the body against invading microorganisms and foreign substances. The lifespan of these cells varies depending on the type of cell and its function.

Types of White Blood Cells and Their Lifespan

1. Neutrophils - These cells are the most abundant type of white blood cells and are responsible for fighting bacterial infections. Their lifespan is about 5-10 hours in the bloodstream, followed by 1-2 days in the tissues.

2. Eosinophils - These cells are responsible for fighting parasitic infections and are involved in allergic reactions. Their lifespan is about 8-12 days.

3. Basophils - These cells are involved in allergic reactions and inflammation. Their lifespan is about a few hours to a few days.

4. Lymphocytes - These cells are responsible for fighting viral infections and producing antibodies. They have a lifespan of a few days to several years.

5. Monocytes - These cells are responsible for fighting bacterial and viral infections and have a lifespan of about 1-3 days in the bloodstream, followed by several months in the tissues.

Conclusion

In conclusion, the lifespan of human white blood corpuscles varies depending on the type of cell and its function. Neutrophils have the shortest lifespan of about 5-10 hours, while lymphocytes can live for several years. Understanding the lifespan of these cells is important for diagnosing and treating various diseases and infections.
