Which body system is responsible for the body's immune response?

Digestive system
Muscular system
Immune system
Nervous system

The correct answer is: Immune system

The immune system is specifically designed to protect the body against pathogens, such as bacteria, viruses, and other foreign invaders. It consists of various organs, cells, and proteins that work together to identify and neutralize threats, ensuring the body maintains health and proper functioning. This complex network includes components like white blood cells, antibodies, and lymphatic organs, which constantly monitor for signs of infection or injury. In contrast, the digestive system primarily focuses on breaking down food and absorbing nutrients, while the muscular system is concerned with movement and stability of the body. The nervous system is involved in transmitting signals throughout the body and coordinating responses, but its primary function is not the immune response. Understanding the specific roles of these systems highlights why the immune system is crucial for defending the body against diseases.
