WebbDiscuss positive and negative feedback mechanisms used in homeostasis Describe thermoregulation of endothermic and ectothermic animals Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis (“steady state”). WebbPositive feedback is a physiological mechanism that amplifies a system’s output. In the short term, positive feedback isn’t homeostatic. Rather, it increases a physiological variable in a way that drives a process to completion. Unlike negative feedback loops, positive feedback loops have to be time-limited. 4a. Blood Clotting
