Organization of the Human Body and Homeostatic Mechanisms
- The hypothalamus regulates body temperature through heat generating and conserving activities such as shivering and blood vessel constriction when body temperature drops, and sweat gland stimulation and blood vessel dilation when body temperature rises.
- Homeostatic mechanisms maintain stable conditions in the body through negative feedback, but some operate through positive feedback, which intensifies the change initially instead of reversing it.
- Examples of positive feedback mechanisms in the body include blood clotting and uterine contractions during childbirth.
