Coloured SEM of a sectioned villus from the ileum

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)

Illustration of intestinal villi. These are minute finger-like projections found on the lining of the small intestine. Their role is food absorption

False-colour SEM through the wall of the duodenum
False-colour scanning electron micrograph (SEM) of a section through the duodenum. The duodenal wall has muscle layers (at far left, brown)

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

Intestinal villus cell loss, SEM
Intestinal villus cell loss, coloured scanning electron micrograph (SEM). Close-up of the tip of a villus in the small intestine that has shed a cell from its tip as part of the normal cell

Intestinal villi, the tiny finger-like projections lining the walls of our small intestine, play a crucial role in nutrient absorption. These intricate structures are like nature's own microscopic work of art. Through illustrations and artwork such as F007/7807 and F007/7808, we can visualize the complexity and beauty of intestinal villi. Their delicate yet efficient design allows for maximum surface area within our digestive system. In a light micrograph capturing the colon lining, we witness the intricacy of these villi up close. The image showcases their unique shape and arrangement, providing insight into their function in absorbing water and electrolytes from digested food. Coloured SEM images further highlight the remarkable structure of these villi. From sectioned pieces in the ileum to those found in different parts of the small intestine like jejunum, each image reveals their vibrant colors that make them stand out under magnification. The false-colour SEM through the wall of duodenum gives us an extraordinary glimpse into how these villi extend into our intestines' inner layers. This visualization helps us understand how they facilitate nutrient absorption by increasing surface area contact with chyme (partially digested food). As we explore more SEM images showcasing individual villi from various angles, it becomes evident why they are essential for digestion. Their presence ensures efficient absorption by maximizing contact between nutrients and absorptive cells present on their surfaces.
