, The management of an organism's internal environment and the preservation of
a stable, continuous condition of attributes such as temperature and pH are
referred to as homeostasis.
Feedback: negative and positive
Homeostasis needs a great deal of observation and supervision. Hormones and
the nervous system work together to find and respond to stimuli, resulting in
modifications that return the situation to its original condition. To monitor and
control internal situations, the body employs feedback systems.
The body employs two different sorts of feedback:
Negative feedback
The systems that archive the body's homeostasis are known as negative
feedback. When a body's states changes, effectors react by returning the
condition to its original state.
Positive feedback
Positive feedback does not result in homeostasis, while it might be useful
in certain situations, such as delivery. When a change in the body's
condition causes effectors to magnify the change and push it farther away
from normal, this is known as positive feedback.
