<h3>What is Immune system ?</h3>
A vast network of organs, white blood cells, proteins (antibodies), and chemicals make up your immune system.
- Together, these components of your body's defence system guard you against external invaders (bacteria, viruses, parasites, and fungus) that can lead to illness, disease, and infection.
- A weakened immune system can momentarily be brought on by treatments like anticancer therapies and radiation therapy, despite the fact that it is primarily brought on by certain illnesses, starvation, and specific genetic problems.
