, atmosphere
5. ventilation <Ans> the process of inhaling oxygen into the lungs and exhaling
carbon dioxide from the lungs
6. impaired ventilation caused by <Ans> rib
fracture muscle weakness
c-spine injury
asthma
chronic bronchitis
cystic fibrosis
pulmonary edema
acute respiratory distress syndrome
pneumonia
7. transport <Ans> the availability of hemoglobin and its ability to carry oxygen from
alveoli to cells for metabolism and to carry carbon dioxide produced by cellular
metabolism from cells to alveoli to be eliminated.
