What term refers to resistance to disease that is partially inherited and developed through healthy living?

The correct term for resistance to disease that is both partially inherited and developed through healthy living is natural immunity. This form of immunity arises from the body's natural defenses, which can include genetic factors inherited from parents, as well as environmental factors and lifestyle choices that promote health. Natural immunity is vital because it provides the body with a foundational level of defense against pathogens.

Acquired immunity refers to the immunity that develops after exposure to pathogens or vaccination; it is not inherited, but rather learned. Adaptive immunity, on the other hand, is a subtype of acquired immunity that involves a more specific response to pathogens, often characterized by memory cells that allow the body to respond more effectively upon subsequent exposures. Passive immunity typically involves the transfer of antibodies from one individual to another, such as from mother to child during breastfeeding, and does not involve the recipient's own immune system developing a response.

Understanding these distinctions clarifies why natural immunity is the most fitting term in this context, as it encompasses both genetic predispositions and lifestyle factors that enhance health and resilience against diseases.
