Trachea. Coloured scanning electron micrograph
Trachea. Coloured scanning electron micrograph (SEM) of the exterior of the trachea (windpipe). The trachea links the larynx (voice box) to the lungs. Its lining contains mucus-secreting goblet cells and epithelial cells bearing hair-like cilia (not seen). The trachea is reinforced with cartilage rings, which help to keep the airway permanently open

EDITORS COMMENTS
This print showcases the intricate beauty of the trachea, a vital component of our respiratory system. In this coloured scanning electron micrograph (SEM), we are granted a close-up view of the exterior surface of the trachea, commonly known as the windpipe. The trachea serves as a crucial link between our larynx, or voice box, and our lungs. Its lining is composed of specialized cells that play essential roles in respiration. Among them are mucus-secreting goblet cells, responsible for trapping foreign particles and keeping our airways clean. Additionally, there are epithelial cells adorned with hair-like cilia that facilitate the movement of mucus and trapped debris outwards. To ensure its stability and functionality, the trachea is reinforced with cartilage rings which encircle it like protective armor. These rings not only provide support but also help to maintain an open pathway for uninterrupted airflow during breathing. Through this false-coloured SEM image captured by Science Photo Library's advanced scanning electron microscope technology, we gain insight into both the biological complexity and aesthetic allure present within our own bodies. It serves as a reminder of how intricately designed human anatomy truly is – an exquisite masterpiece crafted by nature itself.
