The immune system is the body's defense 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 many different cells, tissues, and organs that work together to
protect the body. The cells involved are white blood cells, or leukocytes, which come that
combine to seek out and destroy disease-causing organisms.
