Which system helps to protect the body from disease?

• A. Nervous system
• B. Circulatory system
• C. Immune system
• D. Respiratory system

Answer: (C)

The immune system is responsible for protecting the body from disease. It consists of a network of cells, tissues, and organs that work together to defend against pathogens such as bacteria, viruses, and other harmful microorganisms. The immune system identifies foreign invaders, targets them for destruction, and remembers them for future protection through a process known as immunological memory. Key components of the immune system include white blood cells, antibodies, and the lymphatic system, all of which play crucial roles in detecting and eliminating threats to the body's health. The other systems listed have different primary functions. The nervous system primarily facilitates communication between different body parts and coordinates actions and responses. The circulatory system is primarily responsible for transporting blood, nutrients, gases, and waste products throughout the body. The respiratory system is focused on facilitating gas exchange, primarily oxygen and carbon dioxide. While these systems contribute to overall health, it is the immune system that specifically targets and protects the body against diseases.
