Chapter 22, Problem 3TYC
Summary Introduction
Summary:
During swimming competition most swimmers hyperventilate before the race to load up extra oxygen (O2) so that they could hold under water for longer duration. The reason for longer holding of the breath is not what they think. Some swimmers due to such practices have lost consciousness and drowned during such processes. The reason for such wrong thinking and the reason for loss of consciousness are discussed.

- What neural afferents might also contribute to the regulation of ventilation during exercise?arrow_forwardDaniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output". First of all, what basic fact about oxygen loading has Daniel forgotten (a lapse leading to false thinking)? Do you think that hyperventilation will provide him with enough oxygen to increase his endurance during the race?arrow_forwardWhich one of the following statements about the afferent components of the respiratory control system is INCORRECT? Select one: a. In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent. b. In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres. c. Chemoreceptor cells can be found in the carotid body. d. The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.arrow_forward
