What is one of the primary ways the body fights infection?

1. Body secretions

2. Antibiotics

3. Vitamins and minerals

4. Proper nutrition

The correct answer is: Body secretions

The primary way the body fights infection is through body secretions. These secretions include various fluids produced by the body, such as mucus, saliva, sweat, tears, and other secretions that contain antimicrobial properties. For instance, mucus traps pathogens in the respiratory tract, while tears contain lysozyme, an enzyme that can destroy bacteria. These natural barriers and fluids are part of the body’s first line of defense, as they help prevent pathogens from entering the body and offer immediate responses to destroy invaders. Other choices, while important in different contexts, are not primary mechanisms for fighting infection. Antibiotics, for example, are medications that can treat infections but do not play a role in the body's initial defense response. Vitamins and minerals boost overall health and support the immune system but are not direct agents in fighting off infections themselves. Proper nutrition contributes to a well-functioning immune system and overall health but is a long-term support strategy rather than an immediate defense mechanism.
