Overview modeling the marine mammal dive response is a high school-level laboratory lesson designed to enhance students’ understanding of biological concepts such as cellular respiration. The presence of a dive response in humans when the face is submerged in water was studied a lot of mammals have shown to exhibit a dive response known as the mammalian dive reflex. Mammalian dive reflex the mammalian diving reflex optimizes mammals' respiration to stay underwater for a long bradycardia is the first response to submersion. Animal models for investigating the central control of the mammalian diving response. The diving reflex, also known as the diving response and mammalian diving reflex is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, which is. The mammalian diving reflex is a physiological response to diving into cold water, and we can use it to help fight the physical symptoms of anxiety.
