Human digestive system, artwork
Human digestive system, artwork. At top, food from the mouth forms a bolus that is swallowed down the oesophagus. At centre, the bolus is about to enter the stomach (arrow), which secretes acid that breaks down the food. Digested food then passes out of the stomach through the pyloric valve (lower left). Nutrients are absorbed in the small intestine which has a folded surface (centre right) with finger-like protrusions called villi (magnified view at centre left). The villi are lined with absorptive cells, passing nutrients to the blood vessels (red and blue). Lymph vessels (green) and the diaphragm (above stomach) are also shown

EDITORS COMMENTS
This artwork showcases the intricate and fascinating human digestive system. The print captures the various stages of digestion, highlighting the remarkable process that allows our bodies to extract nutrients from food. Starting at the top, we see food being transformed into a bolus as it enters the mouth, ready to embark on its journey through the alimentary canal. The bolus then travels down the oesophagus towards its next destination - the stomach. Here, powerful acids break down the food, preparing it for further processing. The image also highlights an essential component of nutrient absorption - the small intestine. With its folded surface and finger-like protrusions called villi, this organ plays a crucial role in extracting vital substances from digested food. These nutrients are then passed on to blood vessels depicted in red and blue. Additionally, we get a glimpse of lymph vessels represented by green lines and learn about their involvement in maintaining overall gut health. The print is not only visually stunning but also serves as an educational tool for those interested in biology or gastroenterology. It provides a detailed insight into how our bodies function on a physiological level while showcasing anatomical structures such as valves and sphincters that aid in proper digestion. Overall, this artwork beautifully combines artistry with scientific accuracy to offer viewers a deeper understanding of one of our body's most complex systems –the digestive system.
