Verified step by step guidance1
Step 1: Begin by identifying the primary function of each organ system listed in the problem. For example, the skeletal system provides structural support and protection, the digestive system processes food and absorbs nutrients, and the muscular system enables movement.
Step 2: Recall the role of the immune system in the human body. The immune system is responsible for defending the body against pathogens such as bacteria, viruses, and other harmful microorganisms.
Step 3: Understand the components of the immune system, which include white blood cells (leukocytes), lymph nodes, the spleen, thymus, and bone marrow. These work together to detect and eliminate infections.
Step 4: Compare the functions of the immune system with the other systems listed in the problem. The immune system is the only one directly involved in fighting off infections.
Step 5: Conclude that the immune system is the correct answer based on its specialized role in protecting the body from infections and maintaining overall health.
