👉 Visible fluids, often referred to as bodily fluids or fluids visible on the skin's surface, include sweat, sebum (oil produced by sebaceous glands), tears, and mucus. These fluids play crucial roles in maintaining homeostasis, protecting the skin and mucous membranes, and facilitating various physiological processes. Sweat helps regulate body temperature through evaporation, sebum keeps the skin hydrated and protected from environmental damage, tears lubricate and cleanse the eyes, and mucus traps particles and pathogens to prevent infections. Each type of visible fluid contributes uniquely to the body's overall function and health.
