What term describes the body’s ability to resist and destroy infections?

The term that describes the body’s ability to resist and destroy infections is immunity. Immunity refers to the complex biological system that enables the body to identify and eliminate pathogens, such as bacteria, viruses, and other harmful microorganisms. This system includes various components like white blood cells, antibodies, and specialized proteins that work together to protect the body from diseases.

Immunity can be categorized into two main types: innate (or natural) immunity, which provides immediate but general protection, and adaptive (or acquired) immunity, which develops over time as the body is exposed to different pathogens. This ability plays a crucial role in maintaining health and preventing illnesses caused by infectious agents.

The other terms, while related to physical health, do not specifically convey the concept of fighting infections. For instance, endurance refers to the body's capacity to sustain prolonged physical or mental effort, resistance implies an ability to withstand something, but doesn't specifically relate to infection. Awareness relates to the perception or knowledge of a condition rather than the biological processes involved in combating infections.
