Which of these is a condition of deficient supply of oxygen to the body?

asphyxia is deprivation not a deficiency

Apnea is just as correct as asphyxia, the correct answer would be hypoxia as several have mentioned.

Hypoxia is the definition of oxygen not available in sufficient amounts at the tissue level to maintain adequate homeostasis

I think hypoxia is a better answer

I chose hypoxia but now that I think about it asphyxia has to do with the delivery of oxygen to the body and hypoxia is the level of oxyygen in the body.

wrong..... it's hypoxia

hypoxia is a deficiency of oxygen

asphyxia is extreme hypoxia...means you're dead. hypoxic patients need oxygen
