Answer:1. The epiglottis, a cartilaginous, leaf-shaped flap, functions as a lid to the larynx and, during the act of swallowing, controls the traffic of air and food.
2.Air then travels down the throat through the larynx and trachea. Air goes into the lungs through tubes called main-stem bronchi.
3.The human trachea (windpipe) divides into two main bronchi (also called mainstem bronchi), at the anatomical point known as the carina.
4.At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli
5.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges
