1. Your immune system can recognize cells based on the proteins present on the surface of cells. Viruses, bacteria, and other foreign cells are recognized as being different from your own cells and are attacked by your immune system.

Think about it for a second. If you lead an army into battle, and your own army start to shoot each other, what odds do you have of winning against the oposition? If the body starts to kill it's own cells that may be used to kill pathogens, it is immediately weakened
The term that identifies a group of cells working together to perform a similar function is "tissue." Tissues are organized into four main types: epithelial, connective, muscle, and nervous tissues, each serving specific roles in the body. These groups of cells collaborate to carry out functions that contribute to the overall health and operation of organs and systems.
In the human body, microbes:native cells can be anywhere from 10:1 to 20:1, though it may be closer to the lower end of this spectrum.

The immune system will target the body's own cells
A chronic autoimmune disease where the body produces antibodies that attack its own cells is known as an autoimmune disorder. Examples include rheumatoid arthritis, lupus, and multiple sclerosis. In these conditions, the immune system mistakenly identifies healthy cells as foreign invaders, leading to inflammation and tissue damage. The exact cause of these diseases can vary and often involves a combination of genetic and environmental factors.
