What is the Immune system?
The Immune system is a complex system of cells and proteins that fight off foreign invaders, the body has 2 types of blood cells Red and White, Red is the life line of the body carrying Blood, Oxygen etc around the body, the white is the defence of the body.
What does the white blood cells do?
The white blood cells help fight off anything they see as a foreign body. For example you pick up a simple cold, the cold virus is seen as foreign body and the bodies defences attack the virus to make you better
My doctor says I have a weakened Immune system what does it mean and what could cause it?
Ok, Basically it means your body lacks the strength to fight off multiple invaders for example while recovering from a cold you could pick another infection and instead of fighting off both it can only cure the one. There are multiple things that could weaken or damage your immune system for example age, disease etc. Another thing is if your has been subjected to mutilpe injuries.
