What function does the immune system serve in relation to other body systems?

• A. It supports the digestive processes
• B. It protects against pathogens and infections
• C. It regulates temperature and fluid balance
• D. It provides structural support to organs

Answer: (B)

The immune system's primary function in relation to other body systems is to protect against pathogens and infections. This system plays a crucial role in defending the body from harmful microorganisms such as bacteria, viruses, fungi, and parasites. When pathogens invade the body, the immune system recognizes them as foreign and activates a range of responses to eliminate them. This includes the production of antibodies, the activation of immune cells like lymphocytes and phagocytes, and the release of signaling molecules that help coordinate the immune response. By effectively identifying and neutralizing threats, the immune system maintains the overall health of the body, which directly impacts the functioning of other systems, including the circulatory, respiratory, and even the nervous system. A strong immune response prevents the spread of infection and disease, allowing other body systems to function efficiently without the burden of dealing with invasive pathogens. Other functions listed, while important to different body systems, do not directly relate to the immune response in terms of pathogen defense. For instance, supporting digestive processes, regulating temperature, and providing structural support pertain to different aspects of body physiology and do not encompass the primary role of the immune system.
