Homeostasis - negative and positive feedback (thermoregulation and lactation)
Armando Hasudungan・2 minutes read
Organisms maintain stable internal conditions through homeostasis, primarily driven by negative feedback mechanisms like vasodilation and shivering. Positive feedback, like in lactation, can also play a role by amplifying responses in the same direction.
Insights
- Homeostasis refers to an organism's ability to regulate internal conditions despite external variations, like maintaining body temperature within a narrow range.
- Negative feedback is the key process in achieving homeostasis by detecting changes and initiating responses to counteract them, while positive feedback, though less common, can intensify responses in the same direction, as observed in lactation triggering milk production.
