How does HIV affect the body?

HIV destroys a particular variety of white blood cells WBCs that are essential for destroying disease-causing germs. There are several varieties of white blood cells in the human body.

Of all these, lymphocytes form about twenty five percent of the total white blood cells count in the body.

When the B cells come in contact with a disease causing agent such as bacteria or virus, they secrete large volumes of antibodies chemical substances that can destroy the disease causing germs.

The main functions of B cells are to search, identify and then bind with the diseases causing germs.

The T cells are lymphocytes that have traveled through a small gland called the thymus gland, which is situated in the middle and upper part of the bonny cage of the chest.

When a disease causing germ enters the body, the T cells produce several new copies of itself. Each T cell contains chemical substances that can destroy the specific disease causing germs.
