Parts of the Immune System that Protect Against Infection
... LET’S REDEFINE THE term “immunity.” Immunity is commonly referred to in a broad sense to represent the processes of providing protection. In people, though, we tend to think of it in narrow terms, frequently focusing on the adaptive components — T and B lymphocytes. Yet, in reality, protection from ...
