Through their nose and mouth using their lungs and diaphragm.
No, sea turtles have lungs that can quickly refill when they come up to breathe on the surface of the water. Green and Loggerhead turtles can hold their breath for about 4 to 5 minutes during a routine activity. But Loggerheads are known for longer dives.
