which of the following constitutes total lung volume?
residual volume and vital capacity
tidal volume, inspiratory reserve volume, and expiratory reserve volume
residual volume and tidal volume
vital capacity and tidal volume
question 7
1 pts
the pco₂ in the atmosphere is:
less than in the alveolar air.
greater than in the alveolar air.
equal to the alveolar air.
greater than arterial blood.
question 8
1 pts
which gas law deals with the solubility of gases in solution?
dalton
henry
boyle
charles

Explanation:

• Question 6: Total lung volume is the sum of residual volume and vital capacity. Vital capacity is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume.
• Question 7: The partial pressure of carbon dioxide (\(PCO_2\)) in the atmosphere is less than in alveolar air. Alveolar air has a higher \(PCO_2\) due to gas exchange in the lungs.
• Question 8: Henry's law deals with the solubility of gases in solution. It states that the amount of a gas dissolved in a liquid is proportional to the partial pressure of the gas above the liquid.

Answer:

• Question 6: Residual volume and vital capacity
• Question 7: less than in the alveolar air
• Question 8: Henry
