Some athletes prepare for competition at sea level by sleeping in a tent in which PO2 is kept low. When climbing high peaks, some mountaineers breathe from bottles of pure O2. In a short essay (100150 words), relate these behaviors to the mechanism of O2 transport in the human body and to physiological interactions with our gaseous environment.

QUESTION:
Some athletes prepare for competition at sea level by sleeping in a tent in which PO2 is kept low. When climbing high peaks, some mountaineers breathe from bottles of pure O2. In a short essay (100150 words), relate these behaviors to the mechanism of O2 transport in the human body and to physiological interactions with our gaseous environment.
ANSWER:Oxygen (O2) is essential for human cells to survive and maintain proper cell function. The human body has evolved to efficiently transport oxygen from the environment to the tissues and organs for metabolic purposes. During exercise, the body requires an increased oxygen volume to meet the metabolic demand of muscle cells. This process is accomplished through a combination of physiological behaviors and gaseous environments.
At sea level, athletes will often practice altitude simulation by sleeping in a tent that is kept at a low oxygen partial
