Composition of air and ventilation perfusion mismatch

Questions:

What is the normal barometric pressure at sea level ?

Give the normal values of PaCO2, PaO2, PvCO2, PvO2?

What is the difference between anatomical and physiological dead space?

Both ventilation and perfusion decrease from bottom to top, yet ventilation perfusion ratio increases from bottom to top. Explain

Draw a diagram showing ventilation perfusion ratio from bottom to top in lungs.

Differentiate between pulmonary and alveolar ventilation.

What are the conditions in which ventilation perfusion mismatch can occur?
