For example, it produces cytotoxic T cells. It also activates our B cells into plasma cells and memory B cells. And that begins the process of defending and protecting our body from these pathogens.

They basically engulfed our antigen and then they present that antigen on this special type of protein membrane complex known as the major histocompatibility complex, class Two.
