7. Neutrophils
If you have a cut that has become infected then you are likely to see pus coming from the area. Pus can also come from a number of other types of infection, such as eye infections. Pus is formed from the discarded ‘bodies’ of white blood cells and pathogens on the front line of the battle against infections.
Pus is made up predominantly of neutrophils, a type of white blood cell. They take on fungi and bacteria directly by first killing them and then digesting them. While pus is a sign that your body is responding to a threat, medical attention may be necessary because excess pus can also mean your immune system is struggling to cope with the problem.
