Explanation:
Our immune system is essential for our survival. Without an immune system, our bodies would be open to attack from bacteria, viruses, parasites, and more. It is our immune system that keeps us healthy as we drift through a sea of pathogens.
This vast network of cells and tissues is constantly on the lookout for invaders, and once an enemy is spotted, a complex attack is mounted.
The immune system is spread throughout the body and involves many types of cells, organs, proteins, and tissues. Crucially, it can distinguish our tissue from foreign tissue — self from non-self. Dead and faulty cells are also recognized and cleared away by the immune system.
If the immune system encounters a pathogen, for instance, a bacterium, virus, or parasite, it mounts a so-called immune response. Later, we will explain how this works, but first, we will introduce some of the main characters in the immune system.

Hawaii, which eventually became the 50th<span> U.S. state, was annexed in 1900. During this period the United States established itself as a world power. Some historians believe that one thing President McKinley did for the nation was inadvertent when he made the decision to pick Theodore Roosevelt as his running mate for the 1900 election, and as a consequence, bequeathed the presidency and the welfare of the country to him</span>

Hope this helps!
