GAS EXCHANGE AND OXYGENATION ATI 2026
PULMONARY FUNCTION PRACTICE SET
ANSWERS FULL SOLUTION
◉ Residual volume.
Answer: Volume of air remaining in the alveoli after expiration
◉ Forced vital capacity.
Answer: The amount of air that is expelled from the lungs in 1
second during forced expiration ( the maximum amount of air you
can forcibly exhale from your lungs after fully inhaling)
◉ Vital capacity.
Answer: Maximum volume of air that is expelled after maximal
inspiration (not in a forced manner)
◉ Total lung capacity.
Answer: Volume of air remaining in the lung after maximal
inspiration
◉ Pulmonary circulation.
, Answer: The movement of blood from the heart to the lungs from
the capillaries for gas exchange and back
◉ Diastole.
Answer: The relaxation phase of the cardiac cycle where the heart
muscle is relaxed and the chambers of the heart fill with blood
◉ Systole.
Answer: The contraction phase of the cardiac cycle when the mitral
and tricuspid valves close and blood is ejected into the aorta and
pulmonary arteries
◉ Cardiac output.
Answer: The volume of blood ejected by the heart ventricles in one
minute
◉ Stroke volume.
Answer: Volume of blood ejected by the left ventricle during one
contraction
◉ Preload.
Answer: The blood remaining in the left ventricle at the end of
diastole prior to the next contraction
