Unformatted text preview: Introduction to the Bio 416L Lab Name(s) The Diving Reflex (30 pts) Instructions You may work in groups of ≤ 4, with students from your lab section , to complete and turn in this assignment. All answers may be handwritten on this sheet, but graphs must be computer-generated. Submit this assignment in lab during the week of Feb 4 th . Introduction A toddler falls into a swimming pool in sub-freezing weather during a brief lapse in supervision. Minutes pass before his parents discover his whereabouts. Upon removal from the pool, he appears lifeless. His frantic parents wrap him in a blanket and attempt CPR. By the time EMS arrives, normal color has returned to the child’s skin and he is breathing. The child survives this near-drowning with no apparent brain damage or other repercussions. One explanation of the ability of humans, particularly children, to survive near-drowning is a physiological mechanism known as the diving reflex. This reflex will serve as a springboard for review of important skills such as library and on-line searches, experimental design, critical thinking, graphing, and interpreting graphs. You will also be asked to recall what you’ve learned about regulation of the cardiovascular system, and apply it to a real-life situation. And you might need to know the cranial nerves! Background Find a source of information about the diving reflex. You may use an on-line source. 1. Is the diving reflex found only in humans? Elaborate. It is found in other mammals besides humans such as in seals, otters, dolphins, and other aquatic mammals....
