Bohr's Law
Boyle's Law
Charles's Law
Dalton's Law
Henry's Law. - Answers Boyle's Law
Boyle's Law describes the relationship between pressure and volume in a closed space.
Henry's Law is related to a gas diffusing into and out of water and its relationship to its partial pressure.
Dalton's Law is related to the independence of partial pressures. Charles's Law is related to the
expansion of gases when heated. Bohr's Law is related to electrons rotating around the nucleus of an
atom.
Which gas is the most common in the atmosphere?
Hydrogen
Carbon dioxide
Nitrogen
Helium
Oxygen - Answers Nitrogen
When you think of the air we breathe, your first thought is probably oxygen; however, we have more
nitrogen in our atmosphere than any other gas. Air is around 78% nitrogen, 21% oxygen, and 0.4%
carbon dioxide, with helium and hydrogen only being found in trace amounts.
Which is not considered a conducting zone structure?
Trachea
Pharynx
, Bronchioles
Larynx
Alveoli - Answers Alveoli
The conducting zone consists of the nose, nasal cavity, pharynx, larynx, trachea, bronchi, and
bronchioles.
The respiratory zone consists of the respiratory bronchioles, which contain the alveoli.
In spirometry, what is the definition of tidal volume (TV)?
The volume of air inhaled or exhaled during a normal, quiet breath.
The maximum volume of air that can be inhaled after a normal inhalation.
The volume of air remaining in the lungs after a maximal exhalation.
The maximum volume of air that can be exhaled after a normal exhalation. - Answers The volume of air
inhaled or exhaled during a normal, quiet breath.
Tidal volume (TV) represents the basic amount of air moved with each normal, quiet breath.
Residual volume (RV) is the volume of air that remains in the lungs after a maximal exhalation.
Inspiratory reserve volume (IRV) is the maximum volume of air that can be inhaled after a normal
inhalation. Expiratory reserve volume (ERV) is the maximum volume of air that can be exhaled after a
normal exhalation.
Which lung volume represents the air that remains in the lungs after a maximal exhalation and never
leaves, maintaining lung elasticity?
Expiratory reserve volume (ERV)
Residual volume (RV)
Inspiratory reserve volume (IRV)
Tidal volume (TV) - Answers Residual volume (RV)
