Hypoxia correct answer: Reduction in partial pressure of o2 resulting in impairment of function hypoxic hypoxia correct answer: Insufficient pressure of O2 in the air; e.g. flying at altitude hystotoxic hypoxia correct answer: A toxin that interferes with absorption of O2 in blood; e.g. cyanide poisoning Stagnant Hypoxia correct answer: results from the inability of blood to carry oxygen to tissues fast enough to sustain their needs (heart failure, circulatory shock). Hypemic Hyp...
