The human immune system is the body's defense against infectious organisms and other invaders. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. In most cases, the immune system does a great job of keeping people healthy and preventing infections; however, problems with the immune system can lead to illness and infection.
