Document Summary

Acb lecture 2 (36) trachea, pleurae, lungs. Sternum is most anterior part of thoracic cavity. Carina: contracts when you sneeze, it will accelerate the air up to a speed of about 165km/h. Anatomical relationships: larynx, trachea, and posterior to the trachea is the esophagus, anterior to the trachea are the. Trachea brachiocephalic arteries and veins: apex of lung sits inferior to the 1st rib. Superior deep view: esophagus sitting behind trachea, aorta and brachiocephalic arteries and veins sitting just anterior to that in the mediastinum. Artery r o i r e t s o. Lateral view: after primary bronchi, we branch into secondary bronchi (aka lobar bronchi) In right lung, have 3 secondary bronchi and 3 lobes: each of the secondary bronchi will supply a lobe of, superior lobar bronchus supplies superior the lung lobe. Inferior lobar bronchus supplies inferior lobe the middle and inferior lobe: middle lobar bronchus supplies middle lobe, oblique fissure separates middle & inferior lobe.
