Gas exchange occurs in the alveoli in the respiratory system. The thin-walled structures allow diffusion of gases into and out of the capillaries.
in the alveoli
Gas exchange does not occur in the respiratory tract, it occurs in the alveoli.
The gas occurs by simple diffusion through the cells.
in your respiratory system
Yes gas is transferred through the alveolar/capillary membrane in the alveolus. Gas moves from the alveolar air sacs to the pulmonary capillaries.
the respiratory system brings oxygen to the blood and removes the waste gas carbon dioxide
The Respiratory System regulates breathing and gas exchanges within an organism. In humans, this system includes the lungs, airways, and respiratory muscles.
The main gas inhailed by the respitory system is oxygen.

The respiratory system does not contain any structure that filters air. The trachea and bronchus are lined with a mucous membrane that helps trap debris and carry it out of the body, but this is not a filtration system.
