How do the body's systems work together to respond to an infection?

• A. The digestive system stops functioning
• B. The immune system detects pathogens, and the circulatory system mobilizes white blood cells to the site
• C. The endocrine system releases energy reserves
• D. The integumentary system blocks the pathogens

Answer: (B)

The body's systems work collaboratively to ensure a coordinated response to infection, and one of the most crucial interactions occurs between the immune system and the circulatory system. When pathogens invade the body, the immune system is responsible for detecting these harmful organisms. Specialized cells within the immune system identify and respond to the presence of pathogens, such as bacteria and viruses. Once the immune system has recognized these invaders, the circulatory system plays a key role in the response. It transports white blood cells—such as lymphocytes and phagocytes—from various parts of the body to the site of infection. These white blood cells are essential for combating the pathogens, as they act to neutralize and eliminate them through various mechanisms, including engulfing them or producing antibodies. This collaborative action not only addresses the immediate threat posed by the infection, but it also enhances communication and alerts other bodily systems to engage in supporting roles. For example, the inflamed area can signal the release of additional chemicals that might attract more immune cells. This synergy illustrates how the body's systems are interconnected and work in concert to maintain health and respond effectively to challenges such as infections. In contrast, other options reflect less accurate responses to infection. For instance, the digestive system does not typically stop functioning as
