Take the Plunge: Demonstrating the Diving Reflex

Wednesday, August 10, 2022

10:00–11:00 AM (PDT)


Easily Demonstrate the Diving Reflex in the Lab Using Sensors and a Bowl of Cold Water

All marine mammals have a reflex for diving in cold water. When cold water contacts the face and nostrils during a dive, heart rate and cardiac output decrease dramatically as blood is shunted away from the extremities and directed to the vital organs. A much smaller version of the diving reflex occurs in humans. In this webinar, we will demonstrate how you can teach your students this biological concept using our Vernier Graphical Analysis Pro app, Vernier sensors, and a large bowl of cold water.
