AHS 100 Chapter 10: The Respiratory System- Pulmonology
❏The main job of the respiratory system is to deliver oxygen to the
blood and carry carbon dioxide away from it. As we inhale, breathing
in, we are taking in oxygen rich air. As air passes through the
respiratory tract, it is cleaned, warmed, and moistened. The air
reaches its end point in the lungs, where it comes in contact with the
blood. There oxygen is exchanged for carbon dioxide. Finally the
waste air passes back out through the nose and mouth (exhale).
❏10.1: Word Parts of the Respiratory System
❏Upper Respiratory system
❏Adenoid: adenoid/o
❏Tonsil: tonsil/o
❏Nose: nas/o, rhin/o
❏Palate: palat/o
❏Mouth: or/o
❏larynx(voice box): laryng/o
❏pharynx(throat): pharyng/o
❏trachea(windpipe): trache/o
❏The entry point for air into the body is primarily through the
nose, with some air entering through the mouth. The nose
serves to warm, clean, and moisten the air. The nose consists
of two nostrils(nares), a septum, and tube- shaped cartilage
inside the nose(turbinates). The nose is very vascular, it
contains many blood vessels, which is why the nose tends to
bleed easily. The blood in these vessels warms the air as it
enters the rest of the respiratory tract. In addition, multiple
hairs line the nose and filter out dust and other particles.
Finally the nose produces mucus, which helps clean and
moisten the air.
❏The air passes through the nose or mouth and proceeds into
the throat(pharynx). There are three parts to the pharynx: the
nasopharynx, the oropharynx, and laryngopharynx. The
laryngopharynx contains the vocal cords (larynx). When air
passes across the cords upon exhalation, the cords vibrate at
certain speeds. These vibrations make sounds, which we use to
form speech. The air continues down the windpipe(trachea).
The trachea is surrounded by bumpy rings of cartilage that
prevents it from caving in.
