Okay, first thing is a cylinder of compressed air (or other gas that you're going to breathe ... could be Nitrox or another mix). Connected to the cylinder is your first stage regulator. This regulator brings the pressure of the air down from what it is in the tank (at the beginning of the dive, around 3,000 psi) down to about 150 psi. Then you have a high pressure hose (after all, 150 psi is still quite a bit of pressure). And finally at the other end of the high pressure hose is your second stage regulator, which reduces the pressure from 150 psi to "ambient" pressure ... meaning the pressure that you're at. Also, it should go without saying, you would also need WATER to breathe underwater. :-)
What else can I help you with?

What IQ do you need to breathe?

Does a catepillar need oxygen?

Why do scuba divers need math?
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
Why do scuba divers need to bring oxygen tanks while fishes do not?
Because fish have gills and can breathe under water and humans do not
Before a diver dives will he will take a deep breath or hyperventilate?
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
Why do people use air?
We need air to breath. Otherwise we would suffocate and die. That is why scuba divers have special equipment to allow them to have air to breath underwater.
What do scuba divers need for a good education?
Like all adults or older teenagers; scuba divers need English and Maths also physics and scuba diving training. Hope I answered your question xx
Do you need to have gills to breathe underwater?
Yes, you do need gills to breathe underwater. Gills process the water through them that makes the water allowed to go through the animal's body without drowning them. Gills are the only thing that keep the animals that live underwater, alive. they also don't make you breath the air in-you breath the oxygen in the water!
Are scuba divers fat?
Generally no. They need to be quite fit to be able to swim in the water :)
Can garden snails breathe underwater?
No, garden snails cannot breathe underwater as they require air to breathe. They have lungs and need to surface to breathe air.
Do penguins need air to breathe underwater?
yes penguins do need air to breath underwater.
What do scientists use scuba gear for?
Logically, for self contained underwater breathing. Zoologists are scientists too! and when they study animals under water, they need to breathe. SCUBA tanks are also used to charge certain air guns and cannons for ballistics testing and such.
Is there enough oxygen under water?
No, there is not enough dissolved oxygen in water for humans to breathe. Aquatic animals have adapted to extract oxygen from water using gills, while humans would need specialized equipment like scuba gear to breathe underwater.
Can land snails breathe underwater, and if so, how do they do it?
No, land snails cannot breathe underwater. They have lungs and need air to breathe. If they are submerged in water for too long, they will drown.
