Foreign body from trachea most common goes to right bronchus due to ?
assistant
The correct answer is  Trachea bifurcates at Carina (at lower border of T4 veebra at T4-T5 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.
