What type of immunity is partially inherited and partially developed through healthy living?

Natural immunity refers to the body's innate ability to fight off pathogens and disease through both genetic (inherited) factors and lifestyle choices that promote health. This type of immunity is established from birth and strengthened by exposure to various infections and environmental factors throughout life.

The inherited component includes genetic factors that can influence an individual's susceptibility to certain diseases or their ability to mount an immune response. For example, some people may inherit genetic traits that provide a stronger natural defense against specific infections. The developed aspect of natural immunity comes from maintaining a healthy lifestyle, which can include proper nutrition, regular exercise, adequate sleep, and minimal stress. These factors can strengthen the immune system over time and enhance the body's ability to fight off diseases naturally.

Active immunity, by contrast, typically requires exposure to the pathogen and involves the body producing its own antibodies, often through vaccinations or previous infections. Passive immunity involves the transfer of antibodies from one individual to another, such as through breast milk or injections. Artificial immunity involves deliberate exposure through vaccinations.

Therefore, natural immunity uniquely encompasses both inherited characteristics and lifestyle influences, making it the best choice for this question.
