The rate of respiration decreases in water due to atmospheric pressure (similar to when you climb up a mountain, you cannot breathe easily).
If you're wondering why the shape of the container is cylindrical, it's to keep the water pressure even around it so that it doesn't break nearly as easily as a square one, for example.
Oxygen needs to be compressed in a diver's tank to increase the amount of oxygen that can be stored in the tank. Compressing the gas allows divers to carry enough oxygen to sustain them while underwater for a longer period of time without the tank becoming too large and unwieldy.

An aqualung is a piece of equipment consisting of an oxygen tank and breathing apparatus used by divers to allow them to breathe underwater at depth.
Because fish have gills and can breathe under water and humans do not
A scuba tank holds compressed air or a mix of gases, typically oxygen and nitrogen, that divers breathe underwater. The tank allows divers to stay submerged for extended periods by providing them with a continuous air supply.
They don't breathe normally on their own.They have to use pressure regulators to breathe naturally, overcoming the extreme pressure deep underwater.A snorkel and oxygen tank help the divers breathe when they are underwater.
yes, basically you're just saying what scuba-divers do
Nitrogen is used in air tanks to dilute the oxygen content, reducing the risk of oxygen toxicity for the divers or miners. This helps prevent certain health issues that can arise from breathing high levels of oxygen under pressure, such as seizures or respiratory problems.

The use of an oxygen analyzer would be advised. Most nitrox and technical divers have one.

Patients cannot bring or use their own oxygen tanks on an airplane; therefore the patient must leave his or her portable oxygen tank at the airport before boarding.
