Trachea is a hollow windpipe which is connected through larynx to bronchi of lungs. It is a part of respiratory system. It consists of 20 cartilage rings which are hard muscles. It is made of smooth and moist tissues. On an average, the diameter of trachea may differ from 1.5 - 2 centimeters. It starts at the bottom of the larynx and ends at the carina, where the trachea divides into the left and right central bronchi.
