But these B lymphocytes must associate with the helper T cells to actually become these two different types of cells. So these two different divisions although they are divisions, they have to work together to actually carry out this process of defending and protecting our body from pathogens. Now, the humoral immunity system is actually very effective against bacterial cells, different types of parasites, fungi, viruses, as well as toxins that enter our tissue of our body. Now, let's move on to our cell mediated immunity. Now, the cell mediated immunity also involves a special type of leukocyte known as the Tea lymphocytes. So belymphocytes are the humoral immunity but T lymphocytes are part of our cell mediated immunity.
