Food & bacteria in the ileum, SEM
Food and bacteria in the small intestine. Coloured scanning electron micrograph (SEM) of food debris (yellow) and normal intestinal bacteria (purple) on villi (projections, red) in the ileum. The ileum is the final section of the small intestine, before it becomes the large intestine. A variety of bacteria populate the human digestive system. In the small intestine they help to digest food and prevent harmful disease-causing bacteria from proliferating. Rod-shaped bacteria are called bacilli. Magnification: x475 at 6x7cm size

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate world of food and bacteria in the small intestine. In this coloured scanning electron micrograph (SEM), we can observe a fascinating symbiotic relationship between food debris, normal intestinal bacteria, and villi. The ileum, which marks the final section of the small intestine before it transitions into the large intestine, is teeming with life. The yellow specks represent remnants of consumed food while purple hues depict normal intestinal bacteria. These tiny organisms play a crucial role in our digestive system by aiding in food digestion and preventing harmful disease-causing bacteria from thriving. The red projections known as villi are essential for nutrient absorption. They provide an expansive surface area where both food particles and beneficial bacteria interact harmoniously to support healthy digestion within our human body. Through this SEM image magnified at x475, we gain insight into the biological wonders that occur within us every day. It reminds us of the complexity and beauty found within our own anatomy – a testament to how different organisms coexist symbiotically to maintain overall well-being. This remarkable photograph serves as a reminder of nature's intricate design and highlights the importance of maintaining a healthy gut ecosystem for optimal bodily functions.
