Ans. is 'c' i.e., More horizontal Trachea bifurcates at Carina (at lower border of T4 veebra at T4-T, disc space) into right and left principal (primary) bronchi.Right principal bronchus is wider, shoer (2.5 cm long), and more veical in the line of trachea (25deg with median plane.Therefore a foreign body is most likely to lodge in the right bronchus.Right bronchus divides into epiaerial and hypaerial bronchi, passing respectively above and below the pulmonary aery, before entering the hilum.Left principal bronchus is narrower, longer (5 cm long) and more horizontal (45deg with median plane). Left bronchus crosses in front of the esophagus producing a slight constriction.Inside the lung it divides into 2 lobar bronchi: upper and lower.
