The immune system

The immune system is very important in protecting us from pathogens.

A pathogen is something that can cause disease like a virus, bacterium or parasite.

If our body comes into contact with a pathogen, our immune system kicks in to try stop it in it’s tracks.

There are 3 types of immunity:

🦠 Innate – this is the immunity we are all born with. It includes the skin and mucous membranes – the first line of defence.

It leads to a general and non-specific immune response.

🦠 Adaptive – this type of immunity develops as we get older. Pathogens have antigens – substances that cause an immune response.

When we come into contact with a pathogen for the first time, our body will form an immune response and create a memory in the form of antibodies.

Should it come into contact with that same antigen in the future, the antibody will recognise that antigen. This leads to an immune response where antibodies bind to the antigens to neutralise the pathogen leading to reduced or no symptoms from exposure.

🦠 Passive – this type of immunity is ‘borrowed’. It is passed on from mother to baby via antibodies passing through the placenta before birth and via breastmilk after birth.

Keep an eye out for next Monday’s post where we will discuss the immune response in more detail.
