Namely, oxygenation brought about important alterations to the sulphur cycle, which provided an environmental niche for sulphur bacteria to create phosphorite beds.
The goal of a breathing exercise is to improve the oxygenation of the cells within one's organism in order to balance the chemical secretions within the body.
The oxygenation of the atmosphere and oceans had altered global biogeochemical cycles and triggered the formation of the earliest worldwide phosphorite deposits.
With enough blood loss, ultimately red blood cell levels drop too low for adequate tissue oxygenation, even if volume expanders maintain circulatory volume.
