The Airways and BIood Vessels
para 1 During inspiration air passes through either the nose(the most com-
mon site)or mouth into the pharynx(throat)，a passage common to
both air and food．The pharynx branches into two tubes，the esopha-
gus through which food passes to the stomach，and the larynx，
which is part of the airways．The larynx houses the vocal cords，
two folds of elastic tissue stretched horizontally across its lumen．
The flow of ai r past the vocaI cords causes them to vibrate，produ．
cing sounds．The nose，mouth，pharynx and larynx are termed the
upper airways．
para 2 The larynx opens into a long tube，the trachea，which in turn bran-
ches into two bronchi，one of which enters each lung。Within the
lungs，there are more than 20 generations of branchings，each resul-
ting in narrower，shorter，and more numerous tubes．The walls of
the trachea and bronchi contain cartilage．which gives them thei r cy-
lindrical shape and supports them．The first ai rway branches that no
longer contain cartilage are termed bronchioles．Alveoli first begin
to appear，attached to the walls of respiratory bronchioles。The
number of alveoli increases in the alveolar ducts，and the airways
then end in grapelike clusters consisting entirely of alveoli．The air-
ways，Iike blood vessels，are surrounded by smooth muscle，the
contraction or relaxation of which can alter airway radius．
para 3 The airways beyond the larynx can be divided into two zones：(1)
The conducting zone extends from the top of the trachea to the be-
ginning of the respiratory bronchioles；it contains no alveoli and
there is no gas exchange with the blood．(2)The respiratory zone，
which extends from the respiratory bronchioles on down，contains
alveoli and there is an exchange of gases with the blood．
