Trachea lining. Coloured scanning electron micrograph (SEM) of the lining of a trachea (wind pipe), showing the cilia (hair-like) and goblet cells (pink). The trachea links the larynx to the lungs. The lining consists of mucus-secreting goblet cells and epithelial cells that are covered in hair-like cilia. Mucus traps debris, such as dust particles or bacteria, in the inhaled air, while the beating of the cilia moves the mucus and particles upwards out of the respiratory tract. This helps to keep the lungs and airways clear and prevent infection. Magnification: x2650 when printed at 10 centimetres wide.
