this exchange takes place in the millions of alveoli in lungs and capillaries that envelop them as inhaled oxygen moves from alveoli to the blood capillaries and co2 moves from the blood in the capillaries to the air in the alveoli

Answer 2

How does Co2 and O2 exchange in the alveoli?

=>Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
