It optimizes respiration by … 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, and is found in all air-breathing vertebrates studied to date. It optimizes respiration by preferentially distributing oxygen stores to the heart and brain, enabling submersion for an extended time. The diving reflex is exhibited strongly in aquatic mammals, such as seals, otters, dolphins, and mu…

For one thing, it helps to conserve oxygen by slowing down our heart rate and directing blood flow to our vital organs. It also helps to protect our lungs from damage by constricting our blood vessels and reducing the amount of air that enters our lungs. short sleeve vests for boysWebb29 maj 2012 · More recently field physiological studies have shown that many marine animals can adjust cardiorespiratory aspects of their diving response depending upon the behavioral situation.
