To start off this discussion, I will explore how both negative and
positive feedback loops help the body to maintain homeostasis.
Homeostasis is “the tendency of biological systems to maintain relatively
constant conditions in the internal environment while continuously
interacting with and adjusting to changes originating within or outside the
system” (Lumen Learning & OpenStax, n.d., para 2). It is the process by
which internal variables are kept at optimal levels to maintain an
environment suitable for normal function. When a stimulus changes one of
these internal variables, a message is sent to the affected body system,
triggering a response by the body, as part of its ability to maintain
homeostasis.
Homeostasis within the body is normally maintained with the help of
something called feedback loops. Feedback loops can be either positive or
negative and they are what control the body’s internal conditions. A
“feedback loop is defined as a system used to control the level of a variable
