The immune system is the body's defence against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.

The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. One of the important cells involved are white blood cells, also called leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.

It is a defence mechanism by a human body that resist the entry of harmful microorganism to enter the body and even it prevents the growth of a similar microorganism in human body It is a process of detection and elimination of pathogens and harmful microorganism by the human body

Immune system involves cells and organs helps in the detection of self and non-self tissues and cells the immune system has evolved to protect the host from a universe of pathogenic microbes that are themselves constantly evolving. The immune system also helps the host eliminate toxic or allergenic
