White blood cells, or WBCs, are like the body's superheroes. They play important roles in keeping us safe from sickness. Let’s break it down in a simple way:

Innate Immunity:

• Some WBCs, like neutrophils and macrophages, are the first ones to respond when we get an infection.
• They move in quickly, surround the bad germs, and let other immune cells know there’s a problem.

Adaptive Immunity:

• This is where another type of WBCs, called lymphocytes, come in.
• There are two kinds:
  • B cells make antibodies that fight germs.
  • T cells can directly attack infected cells or help organize the immune response.

In short, WBCs are super important for keeping our bodies safe and making sure we can fight off specific germs when they try to invade!
