What is a possible function of antibodies found in sweat?

• A. To nourish the skin cells
• B. To control bacterial growth
• C. To enhance skin color
• D. To improve elasticity

Answer: (B)

Antibodies found in sweat serve primarily as a defense mechanism, playing a crucial role in controlling bacterial growth on the skin. Sweat contains immunoglobulins, particularly secretory IgA, which can inhibit the proliferation of various pathogens, including bacteria and fungi. This antimicrobial property helps maintain the skin's barrier function and overall health by preventing infections that could arise from microbial colonization. While nutrients and moisture provided by sweat assist in skin health, they are not the primary focus of the antibodies present. Similarly, skin color and elasticity are influenced more by melanin and collagen respectively, rather than by the presence of antibodies. Thus, the function of antibodies in sweat focuses on their protective role in the integumentary system.
