Coloured SEM of a villus of the small intestine
Villus of small intestine. Coloured scanning electron micrograph (SEM) showing a healthy villus of the small intestine. The villus epithelium (lining) is made up of mucus-producing goblet cells (pink) and polygonal absorptive cells (purple). Villi are finger-like projections from the intestinal wall which greatly increase the absorptive surface of this part of the digestive system. Mucus secretions aid the movement of food through the intestines. The small intestine is around 6 metres long, providing a large surface area for effective food absorption. This is the jejunum, the central part of the small intestine. Magnification unknown

EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of a healthy villus in the small intestine. The intricate details are brought to life, revealing the complex structure of this essential part of our digestive system. The villus epithelium, beautifully depicted in shades of pink and purple, consists of mucus-producing goblet cells and polygonal absorptive cells. These tiny finger-like projections called villi play a crucial role in increasing the surface area for efficient food absorption within the small intestine. As we delve into the image, we gain insight into how mucus secretions aid in moving food through the intestines smoothly. With an impressive length of approximately 6 meters, the small intestine provides an extensive absorptive surface for optimal nutrient uptake. Focusing on this specific section known as the jejunum - located at the center of the small intestine - we marvel at its microscopic intricacies that contribute to our overall well-being. While magnification remains unknown, it is evident that this SEM offers us a glimpse into one aspect of human anatomy that is often hidden from plain sight. This remarkable photograph serves as a reminder not only of our body's incredible complexity but also highlights how scientific advancements allow us to explore and appreciate these wonders on a microscopic level.
