The air will now travel through a series of tubes that become smaller and smaller as they repeatedly branch; these tubes, very similar in structure to the "windpipe", are called _bronchi_________. Even tinier tubes continue branching; these tubes contain smooth muscle and cartilage is absent. They are called ___bronchilles_______. The air now arrives at the ______?____, which is the final structure of the conductive zone of the respiratory tract. The respiratory zone of the respiratory tract begins with a tiny tube called a _______?___. The air has nearly reached the end of its journey as it travels down this final tube, called the ____alveoli______. The ______alveolar duct____ has the appearance of a cluster of grapes. alveolar sac__________ are the tiny air sacs where true respiration (gas exchange) can occur between them and neighboring capillaries.
