Skin is a bunker. it wont allow the intruders to get into the body and do more damage and find a habitat suitable for the intruding body to grow. macrophage act as a walk through gate. they are incharge of filtering out any alien body and also any dead cells within the body. anti bodies are like a patrol party or a strike force. these forces are shoot to kill type agents. they are created for a specific threat. like a rapid repsonse force. in case of an intruder,these guys set out and fight the intruding bodies head on. vaccines are like undercover agents in our body. they enemy virus is unaware of thier presence in our body. but when they enter, the vaccines destroys the intruders from within. they can also be termed as the defects from the enemy virus. they are actually from the enemy force but defected to join forces with us.
