However, a critical issue – the identity of the peripheral O 2 chemoreceptors – remained unanswered until methods for cell isolation, culture and patch-clamp recording established that gill neuroepithelial...

...) and the direction of water flow is thought to be countercurrent to the direction of blood flow ( Mallatt and Paulsen, 1986 ). There are no data on ventilation or O 2 extraction at the gills in fed hagfish. However, in fasting hagfish, resting oxygen consumption rate ( Ṁ O 2 ) and O 2 utilization at the gills...

However, these behaviors may have simultaneously hindered lung ventilation such that early snakes may have had to circumvent these mechanical constraints before those behaviors could evolve. Here, we demonstrate that Boa constrictor can modulate which...

...Michael T. Burton; Joseph M. Santin ABSTRACT Chemoreceptors that detect O 2 and CO 2 /pH regulate ventilation. However, recent work shows that lactate ions activate arterial chemoreceptors independent of pH to stimulate breathing. Although lactate rises in the central nervous system (CNS) during...

...Milica Mandic; Yihang K. Pan; Kathleen M. Gilmour; Steve F. Perry ABSTRACT Fish increase ventilation during hypoxia, a reflex termed the hypoxic ventilatory response (HVR). The HVR is an effective mechanism to increase O 2 uptake, but at a high metabolic cost. Therefore, when hypoxia becomes severe...
