Solution
The correct option is A Alveoli
Alveoli are thin, irregular and vascularised bag like structures that arise from the terminal bronchioles within the lungs. These are the structures which are lined by numerous blood vessels. As the alveolus and blood vessel are in close proximity, diffusion of gases take place between the alveoli and blood vessels. Alveoli are the primary sites of gaseous exchange between blood capillaries and the lungs.
RBC acts as a carrier of respiratory gases. Haemoglobin present in RBC binds with oxygen or carbon dioxide during their transportation.
