Give one practical example of negative feedback. - OCR - GCSE Physical Education - Question 12 - 2021 - Paper 1

One practical example of negative feedback is the regulation of blood sugar levels in the human body. When blood glucose levels rise after eating, the pancreas releases insulin, which helps cells absorb glucose, thus lowering blood sugar levels back to a normal range. If the blood sugar level drops too low, the pancreas reduces insulin production, demonstrating a negative feedback loop that helps maintain homeostasis.
