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

The term that refers to the resistance to disease that is both inherited and developed through healthy living is natural immunity. Natural immunity encompasses the body's innate defenses that are present at birth, which provide an initial line of defense against pathogens. Additionally, it includes the immunity that is gained from exposure to various antigens over time, enhancing the body's ability to fight off infections.

Natural immunity is a fundamental concept in understanding how the immune system functions. It operates through various mechanisms, such as barriers like skin, mucous membranes, and specialized cells that respond quickly to pathogens. Healthy living, which may involve a balanced diet, regular exercise, and proper hygiene, can strengthen these defenses and contribute to the body's overall immune response.

In contrast, acquired immunity refers to the immunity that develops after exposure to pathogens or through vaccination, highlighting a different aspect of immune response. Adaptive immunity is a component of acquired immunity that develops specifically to combat particular pathogens. Innate immunity, while related, focuses more on the immediate, non-specific responses the body employs to fight infections from the moment they occur.
