Question

Quizplus · Accepted Answer

The acinus is the functional respiratory unit of the lung. It consists of respiratory bronchioles, alveolar ducts, and alveoli. However, there are no lymphatic vessels associated with the acinus. There are lymphatic vessels in other parts of the lung, such as the bronchi and terminal bronchioles. The absence of lymphatic vessels in the acinus is due to the delicate nature of the alveolar walls, which cannot accommodate the thick walls of lymphatic vessels.
