Final answer:
Consuming adequate fluids helps prevent infection by maintaining a healthy immune system and promoting proper bodily functions. Water flushes out toxins and waste, keeps mucous membranes moist as a barrier, and ensures optimal nutrient transport for the immune system to function well.
Step-by-step explanation:
Consuming adequate fluids helps prevent infection by maintaining a healthy immune system and promoting proper bodily functions. Water is essential for the body to function properly, as it helps flush out toxins and waste products through urine and sweat. It also helps keep mucous membranes moist, which acts as a barrier to prevent pathogens from entering the body.
Additionally, staying hydrated ensures that nutrients are properly transported throughout the body, allowing the immune system to function optimally. Lack of fluids can lead to dehydration, which weakens the immune system and makes it more difficult for the body to fight off infections.
For example, when someone is dehydrated, they may experience dry mouth, decreased urine production, and a weakened skin barrier, making it easier for bacteria and viruses to enter the body. On the other hand, consuming adequate fluids helps maintain a strong first line of defense against pathogens.
