Q

Homeostasis

A

Homeostasis is the process of keeping the conditions in the body the same. It uses negative feedback and feed forward mechanisms to achieve this.
Extra cellular fluid is regulated to ensure enzymes work in optimal conditions and the cells do not “die.”

Q

Feed forward

A

Feed forward occurs in anticipation of a controlled variable changing before it actually does. This can be behavioral (wearing more clothes before going out in the cold) or physiological (salivating when smelling food).

Q

Positive feedback

A

Positive feedback pushes a controlled variable further from the set point, for example when giving birth the female’s uterus is stimulated to have stronger and stronger contractions the more it stretches as the baby passes through during delivery. The contractions only stop once the stimulus is gone i.e. the baby is delivered.
