100% CORRECT WELL DETAILED
What is the main goal of the upper airway - ANSWER humidify the air
what is directly posterior to the nostrils - ANSWER nasopharynx
what is directly posterior to the mouth - ANSWER oropharynx
What components make up the pharynx - ANSWER nasopharynx, oropharynx,
hypopharynx
what is the epiglottis - ANSWER leaf-like structure that covers the trachea
what structure is housed by the larynx - ANSWER the vocal cords
what part of the airway is the most common place for an airway obstruction -
ANSWER the pharynx
how many lobes does the left lung have - ANSWER 2
how many lobes does the right lung have - ANSWER 3
what structure forms the lower portion of the larynx - ANSWER cricoid cartilage
1
, What structures carry air to the trachea to produce sounds - ANSWER pharynx and
larynx
What is the order of airflow through the lower airway - ANSWER trachea - carina-
mainstem bronchi- lung- alveoli
what is the cite of gas exchange in the body - ANSWER alveoli
what structure divides the chest from the abdomen - ANSWER diaphragm
what nerve controls the diaphragm - ANSWER phrenic nerve
what cells are contained in the alveoli - ANSWER t1 and t2 pneumocystis
what is the main goal of t2 pneumocytes - ANSWER produce surfactant that reduce
surface tension and keep alveoli open
what is the act of inhalation - ANSWER 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 - ANSWER 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
