The human body is amazing in its ability to fight off diseases. The body has a collection of cells in the blood steam and tissues that fight off foreign bodies. The most numerous cells in the immune system are called leukocytes, otherwise known as white blood cells. They are created in the bone marrow of a person.
There are other cells that defend the body as well, such as plasma cells, macrophages and a few more. And if someone wanted to get more technical, the leukocytes can be broken down even further. See attachment three. When HIV enters into the body, it attacks these body defending cells. However, because the body has the most of leukocytes, people usually simply say that HIV attacks the leukocytes.
