About This Document

The tendency of the human body to maintain or regulate a stable and constant interior environment is known as homeostasis. This article discusses the homeostatic feedback system, specifically the negative feedback system, and its role in controlling body temperature and maintaining balance. It explains the components of the negative feedback system and how they work together to regulate homeostasis.

The tendency of the human body to maintain or regulate a stable and constant interior
environment is known as homeostasis (Patton & Thibodeau, 2017). Various factors are
responsible for maintaining the homeostasis in order to control the body temperature of a
person. Any variation in the homeostasis of an individual can affect the temperature of the
whole body making the person sick (Marieb & Hoehn, 2007). Negative feedback system is
involved in maintaining the homeostasis of an individual. Negative feedback system
comprise of a loop that opposes the stimulus generated in human body leading to variation in
the homeostatic level of the whole body. There are two different types of homeostatic
feedback system regulating in a human body namely positive feedback system and negative
feedback system (Patton & Thibodeau, 2017). Any variation in the body temperature of an
individual relating to homeostasis is controlled by the negative feedback system.
Negative feedback system consists of three different components including sensor,
control centre and effector. The sensors detect the rise in body temperature, which is
considered as the principal nerve cells and is the primary temperature regulator centre in a
human brain (Marieb & Hoehn, 2007). Any stimulus processed by the sensors activates the
effectors like sweat glands, which will compete against the stimulus and thus will maintain
the body temperature of an individual. In case of negative feedback system, any variation in
the body temperature is noted by the hypothalamus, a structure in brain that regulates the
temperature of the human body (Patton & Thibodeau, 2017). The sensors present in the brain
and periphery trigger the temperature maintaining centre i.e. hypothalamus in the brain. In
case of increased body temperature, hypothalamus will trigger the mechanism to cool the
elevated body temperature at normal. The blood vessels will dilate, which will lead to
increased blood flow in order to increase the heat loss into the environment (Marieb &
Hoehn, 2007). This increased blood flow will help the individual to sweat more so that the
evaporation of sweat from an individuals’ skin can help him or her to cool down the
