What is the main goal of the upper airway humidify the air
what is directly posterior to the nostrils nasopharynx
what is directly posterior to the mouth oropharynx
What components make up the pharynx nasopharynx, oropharynx, hypopharynx
what is the epiglottis leaf-like structure that covers the trachea
what structure is housed by the larynx the vocal cords
what part of the airway is the most common place for an the pharynx
airway obstruction
how many lobes does the left lung have 2
how many lobes does the right lung have 3
what structure forms the lower portion of the larynx cricoid cartilage
,What structures carry air to the trachea to produce pharynx and larynx
sounds
What is the order of airflow through the lower airway trachea - carina- mainstem bronchi- lung- alveoli
what is the cite of gas exchange in the body alveoli
what structure divides the chest from the abdomen diaphragm
what nerve controls the diaphragm phrenic nerve
what cells are contained in the alveoli t1 and t2 pneumocystis
what is the main goal of t2 pneumocytes produce surfactant that reduce surface tension and keep alveoli open
what is the act of inhalation 1. active
2. intercostals/diaphragm contract
3. diaphragm lowers, ribs move up and out
4. chest expands which causes neg pressure forcing air into the lungs
, what is the act of exhalation 1. passive
2. intercostals/diaphragm relax
3. diaphragm rises, ribs move down and in
4. chest decreases in size causes positive pressure which pushes air out of the
lungs
where does oxygenated blood go from lungs to the heart and to the circulatory system
what is the main goal of the body buffer system maintain pH by removing co2 via gas exchange
what are characteristics of a Childs airway anatomy 1. smaller nose/mouth
2. tongue takes up more space
3. narrower trachea
4. less rigid and developed cricoid cartilage
5. airway in general more easily obstructed
what is diffusion 1. Movement of molecules from high to low concentration
2. move O2 from alveoli to capillaries
