White blood cells are part of the immune system and help defend the body from antigens.
Innate Immunity
The innate immune system is effective to a certain degree. That said, if the environment is regulated then the body is less likely to get ill. Innate immunity is effective as once the patient matures his immune system will mature due to the B and T memory cells. The memory cells will help the body prepare for the virus once it has arrived. The memory cells will send specialised lymph nodes to the invading pathogen. The B and T memory cells are key to immunity of a virus.
One defence mechanism of the human body is that when a person gets ill or is infected the person will get a fever, this is a method of notifying the person. This is a bodily defence mechanism produced by the immune system, its main purpose is to make it difficult for the virus to multiply prepare for the virus. The body’s pH level will also change to make it less optimal for the virus. The immune system’s mechanism will change depending on the body’s condition. If the body gets cut the immune system will causes inflammation, this will cause red blood cells to come to the
