Capillaries exchange food, oxygen, and carbon dioxide.
Carbon dioxide passes into the blood at the capillaries of the systemic circulation. Then it is released at capillaries around the alveoli.
The capillary bed in the lungs is where the oxygen and carbon dioxide are exchanged.
Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.
In the alveoli
Carbon dioxide is exhaled
Oxygen diffuses from the alveoli into the capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. Carbon dioxide diffuses from the capillaries into the alveoli and is exhaled from the body.
Oxygen is 'transported' from the lung capillaries to the body capillaries - in an inverse fashion carbon dioxide is transported from the body capillaries to the Lung Alveoli - the Answer is 'It is rich in CO2."
