Gas exchange does not occur in the respiratory tract, it occurs in the alveoli.
Gas exchange does not occur in the respiratory tract, it occurs in the alveoli.
In lungs, where the blood charges itself in oxygen.
And in cells where the blood transfers the oxygen to them and charges itself in CO2.
Gas exchange in the respiratory system occurs in the alveoli. In these grape-like clusters of air sacs, oxygen and carbon dioxide diffuse across the thin membrane.

Gas exchange occurs in the alveoli in the respiratory system. The thin-walled structures allow diffusion of gases into and out of the capillaries.
The gas occurs by simple diffusion through the cells.
The respiratory system's role in energy metabolism lies is to allow the exchange of gases to take place in the lungs and tissue cells. Oxygen is needed for certain metabolic reactions to occur and for the production of energy.

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.
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.
Between the avioli and the lungs.
Goblet cells are in the respiratory epithelium, which lines the airways from the pharynx down into the lungs. They secrete mucous.
