If a patient has low blood oxygen levels but their blood is circulating properly, the most likely organ that is functioning improperly is the alveoli. The alveoli are responsible for exchanging oxygen in the air for carbon dioxide in the blood. If the alveoli are not working properly, this exchange may be compromised, resulting in low blood oxygen levels.
