Vedclass · Answer

(D) The presence of a large number of alveoli significantly increases the surface area available for the exchange of gases. In mammalian lungs,the alveolar ducts open into numerous alveoli,which are the primary sites of gas exchange. This structural arrangement ensures an efficient system for the exchange of large volumes of air,including the residual air,by maximizing the contact area between the air and the pulmonary capillaries.

What does the presence of a large number of alveoli around the alveolar duct opening into the bronchioles in mammalian lungs indicate?
