MT 30-BB (Histology Art 2024-2025) 1 year, 4 months ago This illustration contrasts a healthy lung with a smoker’s lung, vividly showcasing the damage smoking can inflict. The healthy lung appears pink and cheerful, representing clear airways and efficient gas exchange. In contrast, the smoker’s lung is darkened and sad, indicating tar buildup and impaired function. The magnified histological view highlights the microscopic damage: the normal pseudostratified ciliated columnar epithelium is often replaced by squamous epithelium in a process called **squamous metaplasia**. This change, a response to chronic irritation from smoke, compromises the lung’s ability to clear mucus and pathogens, increasing the risk of infections and cancer. This image underscores how smoking not only affects lung appearance but alters vital cellular structures.-
It’s surprising to see how smoking affects not just the appearance of the lungs but also causes deeper changes like squamous metaplasia. I didn’t realize how much it could compromise the lungs’ ability to protect themselves. -
This post is very informative, because not only does it show what a lung looks like, but also explains the outcome if one does not take good care of it. It shows how smoking affects the lungs, which is a very powerful issue to advocate for. Moreover, the addition of the magnified histological view of the squamous metaplasia taking place reminds us of how realistic and serious this condition is.
