Respiratory volumes: Tidal volume is the amount of air you inspire (bring in) with a normal breath. Usually around 500ml. Inspiratory reserve volume is the max amount you can suck in after a normal inspiration. Expiratory reserve volume is the max amount you can push out after a normal expiration. Vital capacity is the most air you can breathe out after taking the deepest breath in.
