018 - Positive and Negative Feedback Loops • Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback look is altered. Diabetes mellitus is caused by an alteration in the blood glucose feedback loop. • Do you speak another language?
