Trachea epithelium, light micrograph

Trachea epithelium. Light micrograph of a vertical section through the pseudostratified columnar epithelium from the trachea, the tube in the throat leading from the mouth to the bronchus and the lungs. Cilia are seen across the inner surface (top). These help to move mucus along the trachea from the lungs to the mouth, removing dust, cellular debris and pathogens. Below the cilia are the columnar cells of the tracheal epithelium (pink), with their nuclei at their bases. Below those two layers is a layer of connective tissue (yellow) and blood vessels (red). Magnification: x3300 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate structure of the trachea epithelium, providing a glimpse into the fascinating world of human anatomy. The image captures a vertical section through the pseudostratified columnar epithelium that lines the trachea, which serves as a vital passageway connecting our mouth to the bronchus and lungs. At first glance, one is immediately drawn to the cilia gracefully spanning across the inner surface of this delicate tissue. These tiny hair-like structures play a crucial role in maintaining respiratory health by propelling mucus along the trachea. Through their rhythmic beating motion, they effectively remove harmful particles such as dust, debris, and pathogens from our airways. Beneath these remarkable cilia lie rows of columnar cells forming the pink-hued tracheal epithelium. Their nuclei can be observed at their bases, highlighting their active involvement in cellular processes within this complex system. Further down lies a layer of connective tissue depicted in yellow tones alongside vibrant red blood vessels. This underlying support network ensures proper functioning and nourishment for this essential part of our respiratory system. With an impressive magnification level allowing for detailed examination when printed at 10 centimeters wide, this visually stunning micrograph provides valuable insights into healthy cell and tissue composition while offering an appreciation for our own anatomical wonders.
