the body are supplied with oxygen


Hyperventilation Correct Answer-breathing fast and deep


Hypoventilation Correct Answer-breathing slow and shallow


Hypoxemia Correct Answer-low level of oxygen in the blood; due to
lung or pulmonary circulation disorders; hypoxia may still occur in the
organs and tissues because of poor circulation; possible cause:
HYPOventilation and interruption of arterial blood flow


Hypoxia Correct Answer-oxygen deficiency in the body tissues and
organs, due to hypoemia or perfusion problems; effects depend on the
organs affected; i.e. CNS tissue=abnormal brain function, renal
tissue=abnormal kidney function
