Coughs, colds and flu are all commonly associated with your immune system – but these are only a few of the things the immune system helps to guard us against.

The immune system can sometimes malfunction, causing it to actually attack tissues and leading to auto-immune diseases such as rheumatoid arthritis and lupus.
