They are nearly round and cartilaginous in front, and flat, with muscular and fibrous tissue, behind, and are line<l with mucous membrane. Of these bronchi, one goes to each lung, the right being little more than an inch; the left, about two indies in length. On entering the substance of a lung, the bronclii divide into smaller branches, which again siibdividc, until they are no larger in diameter than one-fiftieth to one-thirtieth of an inch. These are the bronchioli. At the extremity of these smallest branches and open- ing into them are found clusters of small poly- hedral cells, the air-cells, which consist of elastic tissue, with a lining of mucous membrane, and beneath the latter a l.iyer of minute blood-ves- sels.
