Immunity refers to the body's ability to _________________________.

• A. Resist and destroy pathogens
• B. Fight allergies
• C. Circulate blood
• D. Produce hormones

Answer: (A)

Immunity is the body's ability to resist and destroy pathogens. Pathogens are microbes that can cause disease, like bacteria, viruses, fungi, and parasites. The immune system uses barriers (such as skin and mucous membranes) and specialized cells and responses to recognize these invaders, mount defenses, and eliminate them, helping prevent infection. That makes the statement about resisting and destroying pathogens the best description of immunity. The other options point to different bodily functions: circulating blood is a function of the circulatory system, producing hormones is the endocrine system, and fighting allergies refers to a specific type of immune reaction rather than immunity as a whole.
