A Scuba regulator is designed to provide air to a diver via a demand valve system in a regulated and safe fashion.
A Scuba Regulator consists of two stages - a "first" and "second" stage. The first stage which attaches to a scuba tank by use of either a din or yoke valve, reduces the pressure of the air passing through it to an intermediate pressure slightly above the surrounding pressure at whatever depth of water the diver is at.
The part of the regulator that is in the divers mouth is called the second stage, and is a "demand valve" which gives air to the diver each time he inhales. On exhalation the valve closes and the exhaled air is released as bubbles from the exhaust ports built into the bottom of the second stage.
The fist stage of the regulator also has connections for a high pressure hose which is connected to a Pressure Gauge (showing the remaining air pressure in the scuba tank), one or two low pressure hoses to attach to the divers buoyancy control device and drysuit and an extra second stage which is used for emergency situations for use by another diver.
All regulators are designed with a fail-safe mechanism which means that if they suffer any technical problem, the regulator will "free flow" allowing the diver to return to the surface or to an alternate air supply safely.
The first stage of the regulator is used to reduce the pressure in the tank to roughly 150 psi over the ambient pressure. It can then be sent down a hose built to withstand that lower pressure, meaning a smaller, more flexible hose. These hoses are used to supply air to the second stage regulator, power inflators, and other air-driven devices.
The first stage assembly also has one or more high pressure ports which can be used to monitor the unreduced pressure of the tank.

How can a scuba-diver breath underwater?
From a regulator attached to a scuba tank.
How is scuba connected to your respiratory system?
The SCUBA regulator goes into your mouth.
In scuba diving what is the difference between a regulator and an octopus?
Regulator is what you breathe in
What are some scuba gear?
well you have your regulator and your octupus(alternate regulator) your BCD your dive computer
With which of these sports would a regulator be associated?
scuba diving :D
What is it called the thing you put in your mouth when you go scuba diving?
It is called a regulator. To be specific, the part of the regulator that goes in your mouth is called the second stage of the regulator.
Do you need to put a regulator in your mouth when using full face scuba mask?
no
How do you use the word regulator?
My car can't go faster than 150 mph because of the regulator. Check your regulator every time before you scuba dive.
Where can one purchase a scuba regulator online?
Scuba regulators, also called 'diving regulators', are vital for scuba divers to properly obtain oxygen from a tank. Regulators are available for purchase through diving specialty stores such as Prime Scuba, House of Scuba, and Divers Direct.
Why do Dive suits for undersea exploration have which type of device attached to help the diver breathe?
a divice that supplies air to underwater swimmers
What gear do you wear for scuba diving?
BCD, Regulator[first stage], mask, fins, snorkle + other accesories
