Trachea lining, SEM C013 / 7126
Trachea lining. Coloured scanning electron micrograph (SEM) of the lining of a trachea (wind pipe), showing the cilia (hair-like) and goblet cells (orange). 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

EDITORS COMMENTS
This print showcases the intricate lining of a trachea, captured through a colored scanning electron microscope (SEM). The image reveals the remarkable structure and function of this vital respiratory organ. The trachea, commonly known as the windpipe, serves as a crucial link between the larynx and lungs. The lining of the trachea consists of specialized cells that play essential roles in protecting our respiratory system. Goblet cells, depicted in vibrant orange hues, secrete mucus which acts as a trap for debris such as dust particles or bacteria present in inhaled air. Additionally, hair-like cilia cover the epithelial cells found within this lining. These cilia perform an extraordinary task by constantly beating and moving mucus along with trapped particles upwards towards our throat. This mechanism aids in keeping our lungs and airways clear from potential infections or harmful substances. At a magnification level of x2650 when printed at 10 centimeters wide, this SEM image provides us with an up-close view into one aspect of our body's complex biological systems. It highlights both the protective nature and anatomical beauty found within our own bodies. Photographed by Steve Gschmeissner for Science Photo Library, this print offers not only scientific insight but also artistic appreciation for subjects like glands, mucosal layers, cell structures, and more within biology and anatomy fields.
