Answer:

Anatomic dead space measures the volume of air of all the space of the respiratory system except the alveoli while the physiologic dead space includes the volume of air from the respiratory system and alveoli.

Explanation:

Some of the air a person breathes in never reaches the gas exchange but simply fills in the respiratory passages where gas exchange does not occur such as the nose, pharynx and trachea. the term is called dead space air because they are not useful in gas exchange.
The one your are asking is simply a measurement of air in the respiratory system..one that involves the volume of air in the respiratory system except the alveoli (anatomic) and the one that involves the alveoli (physiologic).
