1.	If a man from sea coast goes to Everest peak thenA. His breathing and heart beat will increaseB. His breathing and heart beat will decreaseC. His respiratory rate will decreaseD. His heart beat will decrease
Answer» Correct Answer - a At high alitude , `PO_(2)` of alveolar air falls becouse of low `O_(2)` tension of tissues ,so `O_(2)` is absorbed very quickly from alveoli , thus , inceasing beathing rate. Heart beat also icreases to supply required amount of `O_(2)` to tissues.
