Type I pneumocytes: thin cells that constitute 90% of the surface area, even though less abundant than type II cells in numbers What types of cells compose the alveolar surface? What are the barriers to gas exchange at the alveolar-capillary interface? What is the surface area of alveolar-capillary interface available for gas exchange?ĥ0 to 100 m 2 approximately the size of a tennis court Respiratory bronchioles (branch point 17) What type of epithelium lines the conducting zone?Ĭiliated, pseudostratified columnar (also known as respiratory epithelium)Īt what point in the respiratory tree does gas exchange begin? How many generations until alveoli are present that is, how many branch generations in the conducting zone? How many branches are there in the respiratory tree? How many alveoli are there present in a normal adult? What is the approximate cross-sectional area of the trachea? To allow for dramatic increase in cross-sectional area.
What is the purpose of the branching pattern shown above?
