Is residual volume a synonym for dead space volume? If not, then why?
Answers
Amount of air that remains within lungs after a forced exhalation is called residual volume. This air participates in gasseous exchange but anatomical dead space volume cannot do so.

Residual volume is an amount of air that allows diffusion of gases to continue between pulmonary blood capillaries and alveoli even after a forced exhalation. The volume could never be measured.
Anatomical dead space volume represents an amount of air that does not participate in gaseous exchange because it is retained in the respiratory tract, and can not reach vascularised alveoli.
Generally an young adult breathes in 500ml of air, which is called tidal volume . 150ml of tidal volume occupies anatomical dead space.

uh r wrong in saying so....
Dead Space volume is the amount of air remains in respiratory tract and is not used for gaseous exchange . it is 150 ml
for exampe : Trachea vagarah mein present air...
residual volume is air present in our lungs even after forceful expiration.
it is 1100 - 1200 ml
the main difference can be that the depth is volume has nothing to do with the lungs space while residuel volume is volume of lungs in a particular condition .....
