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.
在清醒的威德尔海豹进行实验性潜水期间，血糖浓度持续下降。从中央循环血液中消耗的大部分葡萄糖以乳酸的形式出现。在潜水过程中，肺优先利用血液中的乳酸而非血糖作为碳源和能量来源，并且它能够将葡萄糖释放到肺静脉血中，以补充可用于脑代谢的供应。
