*Leukocytes and Their Functions*

*Leukocytes and Their Functions*

*Leukocytes, or white blood cells, play a crucial role in the immune system by defending the body against infections and foreign invaders.*

 *Here are the main types of leukocytes and their specific functions:*

1. *Neutrophils*
- *Function*: Act against bacterial infections.
- *Description*: These are the most abundant type of white blood cells and are often the first responders to sites of infection.

 2. *Eosinophils*
- *Function*: Act against parasitic infections and allergies.
- *Description*: Eosinophils are primarily involved in combating larger parasites and are also key players in allergic reactions.

3. *Basophils*
- *Function*: Act against allergies and prolonged infections.
- *Description*: Basophils release histamine and other chemicals that are important in inflammatory responses and allergic reactions.

 4. *Lymphocytes*
- *Function*: Act against viral infections and some lymphomas.
- *Description*: Lymphocytes are critical for the adaptive immune response, including T cells and B cells, which target specific pathogens.

 5. *Monocytes*
- *Function*: Act against bacterial and viral infections, remove foreign particles, and destroy tumor cells.
- *Description*: Monocytes circulate in the bloodstream and can differentiate into macrophages and dendritic cells, which are essential for both innate and adaptive immunity
