The Flu Virus

The Body's Immune Response

The Flu's Effects On My Body

My week of once having the flu was rough to say the least. My body was achy, I felt as if I haven't slept in weeks and I had an extremely high fever. This respiratory infection took a tole on my entire body and even when my fever broke, it still took me a while to get back to my old self.

Pathogens, Antigens, and Antibodies

An Immune Response

An immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful. In responding to the antigen, the body is able to protect itself. In the case of the flu, as a first line defense, the body would create mucus, saliva, and sweat and sweat. As a second line of defense, increased white blood cell production, and fever. With these different reactions, the body is trying to fight off this viral infection.

How Will The Body Be Prepared For This Pathogen In The Future?

To help prevent a virus like the flu from returning, the body creates antibodies against it. Now, if the bacteria, virus, or other foreign substance returns, the immune system will recognize it and destroy it, before effecting the body as it did before.
