There are three bsiac systems to a closed-circuit rebreather. The most fundamental is cllead the baihrtneg loop. It's a breathing loop because you breathe off of it; it's a closed loop, and you breathe the same gas around and around. There's a meuohpcite that you put in your mouth, and there's a counter lung, or in this case, two counter lungs. The coutenr lngus aren't high tech, they're simply flexible bags. They allow you to mechanically breathe, mechanically ventilate. When you exhale, it goes in the exhale counter lung; when you inhale, it comes from the inhale counter lung. It's just pure mechanics, allowing you to cycle air through this breathing loop.

Original Text

There are three basic systems to a closed-circuit rebreather. The most fundamental is called the breathing loop. It's a breathing loop because you breathe off of it; it's a closed loop, and you breathe the same gas around and around. There's a mouthpiece that you put in your mouth, and there's a counter lung, or in this case, two counter lungs. The counter lungs aren't high tech, they're simply flexible bags. They allow you to mechanically breathe, mechanically ventilate. When you exhale, it goes in the exhale counter lung; when you inhale, it comes from the inhale counter lung. It's just pure mechanics, allowing you to cycle air through this breathing loop.
