Question

Which of these are designed to “watch” for things that are foreign to you and get
rid of them?
antigens
antibodies

Antibodies are like the body’s elite secret agents, designed to recognize and combat foreign invaders such as viruses and bacteria. Each antibody is tailored to attach to a specific antigen, much like a lock and key, neutralizing the threat and marking it for destruction by other immune cells. This targeted approach is crucial for maintaining our health and fighting off infections!

On the other hand, antigens are the unwelcome guests that trigger the immune response. They are molecules found on the surface of pathogens or even on allergens that our body identifies as foreign. When detected, these pesky antigens raise the red flag and activate antibodies, prompting your immune system to jump into action to defend against them. It’s like a thrilling game of hide-and-seek, with your body cleverly spotting and eliminating those intruders!
