* White blood cells (WBCs): These are the main soldiers of your immune system. There are different types of WBCs, each with its own role:
* Neutrophils: These are the most abundant type of WBC and act as the first responders to infection. They engulf and destroy bacteria and fungi.
* Macrophages: These are larger cells that also engulf and destroy pathogens, but they can also present pieces of the pathogen to other immune cells, helping to activate the immune response.
* Lymphocytes: These cells are responsible for specific immunity. There are two main types:
* T cells: These cells directly attack infected cells or cancer cells.
* B cells: These cells produce antibodies, which bind to pathogens and help to neutralize them.
So, it's not just one blood cell, but rather a coordinated effort of many different types of white blood cells that work together to fight off germs.
