Immunity: Your Body's Defense System

Immunity is your body's natural defense system
It protects against harmful microorganisms like bacteria and viruses
It helps fight infections and maintain health

The Role of White Blood Cells

White blood cells (leukocytes) are the soldiers of the immune system
They patrol the body to identify invaders
Different types of white blood cells have specific roles

Types of White Blood Cells and Their Roles

Neutrophils: First responders, engulf and destroy bacteria and fungi
Lymphocytes: Involved in specific immunity
- B lymphocytes: Produce antibodies that mark invaders for destruction
- T lymphocytes: Directly attack infected cells and regulate the immune response

How Immunity Works

When a foreign invader enters the body, the immune system recognizes it as a threat
It triggers a series of responses to eliminate the invader
- Inflammation: Localizes infection, attracts immune cells
- Antibody Production: Neutralizes invaders
- Cellular Immunity: T cells attack infected cells
