Place in order the steps of the gas exchange process.

Neurons in the brain stimulate contraction of skeletal muscles that expand the chest cavity. Expansion of the chest cavity causes inhalation of oxygen-containing air into the airways and lungs. = 1,2 From the lung alveoli, oxygen diffuses into blood and red blood cells. The oxygen in red blood cells bound to hemoglobin is transported through the blood by cardiac effort to tissue cells. = 3,4 Carbon dioxide is transported to the lungs to diffuse into the alveoli for removal during exhalation. = 5 The high concentration of carbon dioxide waste resulting from cellular metabolism allows diffusion of this gas into the blood and red blood cells. = 6

Which condition would cause decreased ventilation due to bronchospasm?

Chronic obstructive pulmonary disease (COPD)

Asthma (correct)

High cervical spinal cord injury

Age

Which laboratory test would be used to assess gas exchange?

Prothrombin time (PT)

Arterial blood gas (ABG) (correct)

Liver enzymes

Creatinine
