By fighting off diseases

Explanation:

The immune system is made up of cells, tissue and organs that work together to protect the body and one important cell fights off disease. White blood cells are made in the bone marrow. These white blood cells fight off disease by devouring them. When you get sick, your body automatically increases the amounts of white blood cells to stop the bacteria/germs from invading your body.
