The immune system protects the body from infections and diseases using white blood cells called leukocytes. These cells work together to recognize and destroy foreign invaders, helping the body develop long-term immunity against future threats.
Insights
- The immune system consists of white blood cells that constantly monitor the body for foreign invaders, with phagocytes consuming foreign cells and lymphocytes producing antibodies to destroy them, ultimately leading to long-term immunity.
- Symptoms like high temperatures and swelling during an immune response are beneficial as they hinder the reproduction of bacteria and viruses, showcasing the vital role of a healthy immune system in protecting the body from infections over a lifetime.
