Short duration diving mammals have lung volumes similar to their terrestrial equivalents and dive with full lungs, using the contents as an oxygen store. The oxygen affinity of the blood is related to lung volume. Where the lungs do not represent an oxygen store, the oxygen affinity is low to maximise the unloading of oxygen and to maintain a ...
Hemp fiber is the basic material used in the production of shimenawa, and has been used since ancient times. [10] In Shinto, hemp is regarded as a sacred food with a meaning of purity and fertility.

Some amphibians utilizing cutaneous respiration have extensive folds of skin to increase the rate of respiration. Examples include the hellbender salamander and the Lake Titicaca water frog. [2] Cutaneous respiration in hellbenders accounts for more than 90 percent of oxygen uptake and carbon dioxide excretion. [4]
This constant cycle of carbon through the system is not the only element being transferred. In animal and plant respiration these living beings take in glucose and oxygen while emitting energy, carbon dioxide, and water as waste. These constant cycles provide for a influx of oxygen into the system and carbon out of the system.
