The fluid-filled inner ear called labyrinth v. The membranous labyrinth is filled with a fluid called perilymph vi. The coiled portion of the labyrinth is called cochlea

Read the passage given below and answer the following questions : Scuba apparatus includes a tank of compressed air toted by the diver on his or her back, a hose for carrying air to a mouthpiece, a face mask that covers the eyes and nose, regulators that control air flow, and gauges that indicate depth and how much air remains in the tank. A diver who stays down too Iong swims too deep or comes up too fast can end up with a condition called 'the bends." In this case, bubbles of gas in the blood can cause intense pain, even death.
