Lung lining, SEM
Lung lining. Coloured scanning electron micrograph (SEM) of mucus-producing cells (orange, round) and cilia (yellow) lining a bronchus (lung airway). Mucus secreted here traps bacteria, dust and other particles. Rhythmic movements of the cilia serve to move the mucus and the trapped particles away from the gas-exchanging parts of the lung, and towards the throat, where they can be expelled

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of lung lining at a microscopic level. In this false-colored scanning electron micrograph (SEM), we are presented with a mesmerizing display of orange mucus-producing cells and yellow cilia that line a bronchus, one of the airways in our lungs. The mucus-producing cells, depicted as vibrant orange spheres, play a vital role in our respiratory system. They secrete mucus which acts as a sticky trap for bacteria, dust particles, and other harmful substances present in the air we breathe. Alongside them, the delicate yellow cilia can be seen protruding like tiny hairs. These cilia possess rhythmic movements that serve to propel the mucus and trapped particles away from the gas-exchanging regions of our lungs towards our throat. Through this efficient mechanism, these remarkable structures ensure that any potential threats or irritants are expelled from our bodies before they reach deeper into our respiratory system. This image provides us with an awe-inspiring glimpse into the internal workings of our lungs and highlights their incredible ability to protect us against external pollutants. Science Photo Library has once again captured nature's marvels through their lens, reminding us of both the complexity and elegance found within even the tiniest components of life.
