The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.
The immune system is a system of biological structures and processes within an organism that protects against diseases

The very first line of defence against any invasion of the human body is a set of physical barriers between the inside of the body and the outer world. Defence systems like the skin, tears and the stomach lining might not sound very impressive until you start to think of what happens when they don’t function. Damage to the skin, such as burns or cuts, very quickly leads to complications and infections that before modern-day antibiotics could easily prove fatal.
Once the outer line of defence is breached, the body very quickly starts up its first major attack on the invading substances. This is called innate immunity, and is made up of a collection of white blood cells along with groups of chemical messengers. Innate immunity is activated by the recognition of a set of molecules that are found only on invading substances rather than on cells of the body. Any sign of things such as bacterial lipopolysaccharide, double-stranded RNA and bacterial flagellin will trigger an inflammatory response
