Yes gas is transferred through the alveolar/capillary membrane in the alveolus. Gas moves from the alveolar air sacs to the pulmonary capillaries.

It is carbon dioxide which is collected from different organs of the body by blood
alveolus
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
The process in which oxygen enters the bloodstream through the alveolus and carbon dioxide exits the bloodstream also through the same alveolus to be exhaled.
The bronchus of a lung is the tubes leading up to the alveolus of the lung. The alveolus of a lung is the small air sacs at the end of the bronchi (bronchus). The alveoli is where the gas exchange of oxygen and carbon dioxide takes place.
The adjective for alveolus (singular) or alveoli (plural) is alveolar.
The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.
