1-B 2-C 3-B 4-B | 5 = mitral 6 = 2 7 = about -70 mV 8 = it contracts and flattens, increasing thoracic volume and drawing air in 9 = the small intestine, via villi and microvilli | 10 = The sympathetic ("fight or flight") response increases heart rate and redirects blood flow toward skeletal muscles and away from the digestive tract, which is why digestion (and its associated systems, like gut motility and enzyme secretion) typically slows down during acute stress — the body prioritises the circulatory changes needed for immediate physical action over the comparatively low-priority process of digesting food.
