Question
Gasping for Air
John, the assistant expedition leader and a seasoned alpinist, helped Tom guide Mark down the steep trail. Mark's breathing, increasingly labored with every passing moment, was loud enough to worry Emily and Pete, the expedition's final climber.
"Geez, do we sound like that?" gasped Pete. "I mean, I'm out of breath, too, but he sounds horrible!" "No, we're not that bad. Remember, that's why we spent the prep month at 15,000 feet. Mark was with us, so he experienced the same physiological changes we did. This," Emily nodded at Mark, "is some sort of problem."
Part II Questions
Fill in the following table about the hormone that was released when the expedition spent their prep month at 15,000 feet.
Source of Hormone Stimulus for Release Target TissuePhysiological Hormone ResponseExplanation / Answer
Answer-
At the high altitude, the atmospheric pressure decreases (hypobaric). Due to which the partial pressure of the oxygen also decreases which leads to hypoxia condition in body.
Erythropoietin is sensitive to the low level of oxygen in blood. Erythropoietin stimulates bone marrow to produce red blood cell and also synthesis of haemoglobin.
