It requires that the respiratory tract be immersed, with the body either in the water or at the surface, and may be performed in a pool or open water (sea, lake, river, etc.). Static apnea is the only AIDA International discipline measuring duration, and one of the three disciplines considered for the international competitions by team, with ...

Sea slugs respire through a gill (or ctenidium). Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.
Acute onset of breathing problems caused by fluid accumulation in lung extravascular spaces induced by immersion, usually in cold water, often with intense physical exertion. Symptoms reported developed during physical activity and usually include dyspnoea/shortness of breath and a cough, often haemoptysis, occasionally chest tightness, chest ...

At least 192 liters (50.7 U.S. gal) of sea water per minute would have to be passed through the system, and this system would not work in anoxic water. Seawater in tropical regions with abundant plant life contains 5–8 mg (0.077–0.123 gr) of oxygen per liter of water. [6] These calculations are based on the dissolved oxygen content of water.
Book gills are flap-like appendages that effect gas exchange within water and seem to have their origin as modified legs. On the inside of each appendage, over 100 thin page-like membranes, lamellae, appearing as pages in a book, are where gas exchange takes place. These appendages move rhythmically to drive blood in and out of the lamellae and ...
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
