First line of defence
The first line of defence is outside the body where they are physical and chemical barriers which protect from pathogens to enter the body.
This is fought by intact skin, tears, saliva, sweat, hairs, urine, vaginal fluids, ear wax. These could cause reflexes such sneezing, coughing, and vomitting.
First line of defence is non-specific, meaning it has a response to the pathogen regardless of its type.
Second line of defence
The second line of defence is also non-specific and responses to the pathogen no matter what type it is. And is non-adaptive, not able to change its response it will have the same response everytime it sees a pathogen. This response contains White blood cells, plasma proteins and phagocytes. These phagocytes engluf the pathogen and kill them before they multiply and damage the rest of the body.
The result of this line of defence is fighting is with a fever, inflammation and redness.
The main role of this line of defence is to kill the pathogen before it harms the body.
