Immune System
Here is the information you need about the immune system:
"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. (IT HELPS PROTECT THE BODY FROM GERMS)
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, that seek out and destroy disease-causing organisms or substances." White blood cells travel through the bloodstream via the circulatory system.
