Final answer:
Adaptive immunity, also known as acquired immunity, includes B-cell and T-cell responses. B cells produce antibodies in humoral immunity, while T cells are involved in cell-mediated immunity.
Step-by-step explanation:
Adaptive immunity, also known as acquired immunity, is a response by the immune system that involves B-cell and T-cell responses.
This type of immunity occurs after exposure to an antigen either from a pathogen or a vaccination. B cells are responsible for producing antibodies, which are involved in the defense against pathogens and toxins in the extracellular environment.
This mechanism of adaptive specific immunity is referred to as humoral immunity. On the other hand, T cells function as the central orchestrator of both innate and adaptive immune responses and are responsible for the destruction of cells infected with intracellular pathogens, which is called cell-mediated immunity.
