Which of the following is used on living tissue to slow the growth of microorganisms?

Antiseptics are specifically formulated chemicals applied to living tissues to decrease the possibility of infection by inhibiting the growth of microorganisms. They are typically safe for use on skin and other body surfaces, allowing for their application in medical settings, such as before surgery or on wounds to minimize the risk of infections.

Disinfectants, on the other hand, are intended for use on inanimate objects and surfaces to eliminate or reduce harmful organisms and are not safe for application on living tissue. Sterilants are used to achieve sterility on inanimate objects and are effective in killing all forms of microbial life, making them unsuitable for living tissue. Sanitizers are used to reduce the number of germs to safe levels on surfaces but again are not designed for application to living tissue. Thus, antiseptics are the appropriate choice for slowing the growth of microorganisms on living tissues.
