Pulmonary metabolism during diving: conditioning blood for the brain

PW Hochachka, GC Liggins, J Qvist, R Schneider, MY Snider, TR Wonders, and WM Zapol

During experimental diving by the awake Weddell seal, blood glucose concentration falls consistently. A large fraction of the glucose consumed from the central circulating blood appears as lactate. During diving, the lung utilizes blood lactate in preference to blood glucose as a source of both carbon and energy, and it is able to release glucose into pulmonary venous blood to supplement the supply available for brain metabolism.
