oxygen store

oxygen store

the total quantity of oxygen stored in various body compartments, including the lungs, arterial and venous blood, and tissues. In a 70-kg human, blood contains about 800 mL of oxygen as oxyhemoglobin, muscles contain about 150 mL as oxymyoglobin, alveolar gas contains a few hundred milliliters, and about 50 mL is dissolved in the tissues.

The team identified a distinctive molecular signature of the oxygen-binding protein myoglobin in the sperm whale and other diving mammals, which allowed them to trace the evolution of the muscle oxygen stores in more than 100 mammalian species, including their fossil ancestors.
Chile John Dow, chairman of the mine operator Pike River Coal Ltd, said each miner carried 30 minutes' oxygen supply - enough to reach oxygen stores in the mine that he said would allow them to survive for several days.

It appears that the whales dive so long that they use up most of their oxygen stores and need to resort to anaerobic metabolism for part of their dives.
Meanwhile, special oxygen stores in their muscles, which they "charge" at the surface, allow them to hunt at depth for over an hour.
The penguins also ration these oxygen stores using physiological tricks unavailable to landlubbers.
Thus turtles optimise their diving behaviour to ensure limited oxygen stores are used in a cost-efficient way, maximising their time at depth.
