Final Exam- Human AnatomyChapter 22: The Respiratory SystemUpper Respiratory Tract(less severe than lower respiratory tract)3 Divisions1.Nose- allows for air intake and sense of smell, moistens and warms entering air,filters inhaled air to cleanse, reasoning chamber for speechIncludes: {O2}Nares (nostrils)- air is taken in through nostrils/ naresVestibule-(“porch entranceway”) waiting area, superior to thenostrils, within the flared wings of the external noseNasal cavity- right and left halves by the nasal septum midlineMedian Nasal Septum- made of perpendicular plate of theethmoid bone, the vomer, and a septal cartilage all covered by amucous membraneoDeviated septum- interfere with respirationIncludes:3 Conchae per side (superior, middle, and inferior)oconchae are covered with ciliated mucous membranes thatfilter, warm, and humidify airOlfactory receptor cells- receive chemicals interpreted as smellsParanasal sinuses- air-filled spaces in the skulloFrontal, ethmoid, sphenoid, maxillaryoMucous membrane linedoDrain into nasal cavityoSinusitis- inflamed sinus membraneHard Plate-anterior portion made of boney tissue and thepalatine bonesoSeparates nasal cavity from oral cavity (mouth)Soft Plate- soft and muscular tissue (posterior portion) extendsmore into the throat regionoSeparates nasopharynx from oral cavityOverview of Respiratory System:The structures and organs that function in air distribution and gas exchangeoFilter, warm, and humidify that air breathed inoInfluence sound productionoProvide for the sense of smellStructures: nasal cavity, nostril (nares), mouth, pharynx, larynx, trachea, left lung, rightlung, rib, right bronchus, left bronchus, intercostal muscles, diaphragm
Uvula- reflects superiorly and the action that closes off thenasopharynx and prevents food from going up and entering thenasal cavity.2.Pharynx (throat)-connects nasal and oral cavities to the larynx and esophagus,and a common tube for the respiratory and digestive systems3 PARTS: nasopharynx, oropharynx, and laryngopharynxNasopharynx- region where nasal cavities open into the pharynxoLocated posterior to the nose, extends to the soft plateoIncludes the Eustachian tubes(maintain pressure in themiddle ear) and the pharyngeal tonsilswhich are locatedon the posterior wall just above the oropharynxOropharynx- tonsils are part of the lymph system and help defendagainst bacteriaoWhere the oral cavity opens into the pharynx, between thesoft palate and the hyoid bone, just behind the tongueoPalatine tonsils- the tonsils that are affected when sick andare usually removed, located in the back of the throat(strep, mono, and can touch each other)oBetween two arches of tissue to the sides of the openinginto the oropharynx from the mouth (most often removedin tonsillectomy), and lingual tonsils, which are located atthe base of the tongueBoth are part of the lymph system and protectagainst bacteria
