Positive feedback: breast feeding, giving birth, and blood clotting are two examples.
Negative feedback: Blood glucose levels, temperature control, and body temperature are two examples.
-Negative feedback: accumulation of an end product of a process slows that process.
-Positive feedback: the end product speeds up its own production. Regulation is important because without it we would bleed out from small cuts because we wouldn't be able to form blood clots. Or we wouldn't be able to form ATP. Regulatory mechanisms help us do the important tasks needed to sustain life.
