What is the difference between homeostasis and negative feedback?
Homeostasis is the stable equilibrium in a body that is responsible for keeping your internal environment at an ideal state. Negative feedback is the product of a stimulus changing the body's state.
Homeostasis is known as ideal state to keep one's body. It is often referred to as "maintaining homeostasis." The body is able to maintain homeostasis through multiple physiological processes. For example, we shiver when we're cold. Shivering warms us up. Another example would be that when we are lacking in sugars, the pancreas pumps out insulin after we eat. This all happens naturally without our control.
Negative feedback occurs in a process at which the body reacts to stimuli affecting it. Whatever this stimuli should be, the body immediately goes into recovery mode to bring it to normal. It is attempting to make up for what our body is lacking due to the stimuli. Not to be confused with positive feedback (which essentially means the effector of the process increases stimuli), negative feedback means the effector of the process reduces stimuli.
