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… WebbThe diving reflex is a response to immersion that overrides the basic homeostatic reflexes, and which is found in all air-breathing vertebrates.

Webb11 apr. 2024 · The diving reflex has a number of benefits. 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. Webb27 sep. 2024 · The dive reflex is a vast physiologic process, but its main mechanisms involve peripheral receptors, neuronal pathways, and chemoreceptors. Once a mammal …
WebbProtective reflexes also influence spontaneous breathing in the very young. Particularly in preterm babies, the pressure of a face mask may induce bradycardia and apneas by stimulating stretch re-ceptors of the trigeminal nerve, known as trigemino- cardiac reflex. 28 This reflex is at the base of the diving reflex which is stimulated upon
