False-colour SEM of villi in the jejunum
False-colour scanning electron micrograph (SEM) of villi in the jejunum of the small intestine. Folds (villi) in the jejunum wall increase the surface area of the small intestine for its role in food absorption. Food digested in the stomach and duodenum is here absorbed through epithelial cells (blue), into blood capillaries contained in each villus. Goblet cells on this surface secrete mucous to protect the villi from digestive pro- cesses, and assist food to pass through the jejunum. Dead desquamating cells seen on the ridges of the villi are coloured yellow and orange. Magnification: x110 at 6x7cm size. Magnification: x170 at 4x5 inch size

EDITORS COMMENTS
This print showcases the intricate and vibrant world of villi in the jejunum, a section of the small intestine. Through false-colour scanning electron microscopy (SEM), we are granted a mesmerizing glimpse into the inner workings of our digestive system. The folds or villi that adorn the walls of the jejunum serve a crucial purpose - to maximize surface area for efficient food absorption. Epithelial cells, depicted in striking blue hues, play a pivotal role in this process by absorbing nutrients from digested food into blood capillaries nestled within each villus. To safeguard these delicate structures from harsh digestive processes, goblet cells generously secrete mucous onto their surface. This protective layer not only shields them but also aids in facilitating smooth passage for food through the jejunum. A closer inspection reveals yellow and orange-colored dead desquamating cells adorning the ridges of these tiny projections. These remnants remind us of the constant renewal and turnover occurring within our bodies as old cells make way for new ones. With magnification levels reaching x110 at 6x7cm size and x170 at 4x5 inch size, this image allows us to marvel at nature's intricacy on an incredibly detailed scale. It serves as a testament to both human anatomy and scientific exploration while shedding light on vital aspects such as gut health, digestion, and nutrient absorption.
