What is the primary function of an antiseptic?

The primary function of an antiseptic is to act as a chemical agent applied to living tissue with the purpose of preventing the growth and reproduction of microorganisms. Antiseptics are essential in medical and veterinary practices as they help to reduce the risk of infection when applied to skin or mucous membranes. They work by killing or inhibiting the growth of bacteria, viruses, and fungi, thereby promoting safer healing and reducing the likelihood of post-surgical or post-procedural infections.

This function contrasts with disinfectants, which are used on inanimate surfaces to eliminate pathogens. While vaccines are also a vital part of disease prevention, they serve a different purpose by stimulating the immune system to create immunity against specific diseases rather than acting directly on microorganisms present on tissues. Thus, the correct choice is clearly aligned with the role of antiseptics in maintaining hygiene and preventing infection in living tissue.
