Marine Mammal DIVING RESPONSE
Laboratory Purpose: n Discuss n Discuss the Diving Response n Test n Test our own response n Collect n Collect data n Graph n Graph & Analyze the Data
What is the Diving Response? nWnWnWnWhat happens to the physiology of the marine mammals? nWnWhy is this useful to them when they are diving?
DATA ANAYSIS n Collect the data n Compute the % difference from resting pulse n Graph your results The graph to the right shows two persons pulse rate as BPM at REST I, Breath hold II, Recovery III, +Bending IV, and Cold Dip V
DRAW YOUR OWN CONCLUSIONS ! n What can cause pulse rate to vary? n Which set of conditions triggered the greatest response? n Is the Marine Mammal Diving Response observed in humans? n How can it help persons survive drowning? survive drowning?
