Solution

(b) alveoli of lungs

The exchange of gases takes place between the alveoli and the pulmonary capillaries. This is known as the pulmonary exchange and is a part of the overall process of respiration or breathing. So these capillaries are woven into the tissue of the alveoli and the exchange takes place in the connective tissue between them.
