Year 13 students took time out from their lunch to learn about baroreceptor reflexes from University of Dundee lecturer Dr Graham Christie. Dr Christie reminded students how to take a pulse. The group then tracked changes in heart rate by measuring each other’s pulses in different positions. Students discovered that heart rates can change when laying down, sitting up and standing. The baroreceptor reflexes tell your heart rate to increase and push more blood to your brain when you stand or move, something they found out as they lay on the floor and then quickly stood up.
The students enjoyed the presentation and the opportunity to ask questions on learning at university. A big thanks to Dr Christie!
