Objective 42:Protect yourself

Non specific Immune system will attack anything foreign tring to enter in our bodies. It consist of twp parts the 1st line of defense and the 2nd line of defense. The 1st line consist of the skin and the mucosae. The 2nd line is made up of antimicrobial protiens, phagocytes, and other different cells found in the body. The 2nd line of defense is used in the inflamatory process.
Specific Immunity targets  more specific foreign invaders, it takes a little bit longer to be prepared for the "fight" than the 1st two above. It consist of the T-cells and the B-cells.
We also an active immunity which can be aquired in two way: naturally and artificially. Natural immunity is when you "catch a bug" and you feel bad. Artificial immunity is what all of us PTA student just had to go and get. It's vaccines, they don't prevent disease, they just help fight off the disease if we get exposed to it, it's basically a fake infection or virus that dosen't kill us or hurt us too bad.
