About The Immune System

What is your immune system?

Your immune system is a network of cells, tissues, and organs that work together to protect your body. Essentially, it is your body’s defence system against infectious organisms and other invaders. 


How does your immune system work?

Through a process called the immune response, your immune system attacks organisms and substances that invade the systems of your body and cause diseases.

Here’s how it works:

• Foreign substances called antigens are detected as they invade your body, sparking the immune response. Several types of cells work together to recognise them and respond.
• These cells trigger a type of white blood cell called B lymphocytes to produce antibodies, specialised proteins that lock onto antigens.
• The antibody marks the antigen to be killed by phagocytes, another type of white blood cell that absorbs antigens, and breaks them down, effectively eating and destroying them.
• Once produced, these antibodies stay in your body, so if your immune system encounters that antigen again, the antibodies are already there to do their job. This is why you usually do not get the exact same virus twice.

Why your immune system needs support

Your gut is the most prominent part of your immune system, representing almost 70% of your immunity due to the huge number of immune cells that reside there. It is therefore important to keep it healthy.
