Illustration of the small intestine

Illustration of the muscle layers and blood supply of the small intestine. The small intestine is a long, complex-layered part of the gut responsible for digestion and absorption of food. Internally it is lined with a mucosa of villi (small project- ions) that create a large surface area for absorp- tion of food into the blood. Externally the small intestine is covered with a serosa (here, white). Between these is a layer of inner circular muscle and outer longitudinal muscle (pink), important in moving food through the intestine by peristalsis. Food absorption into the blood occurs through an extensive network of blood vessels (red), and a lymphatic network (yellow) absorbs fats

EDITORS COMMENTS
This print showcases the intricate details of the small intestine, a vital component of our digestive system. The illustration beautifully depicts the various muscle layers and blood supply that make up this complex organ. The small intestine plays a crucial role in digestion and absorption of food, ensuring that nutrients are properly absorbed into our bloodstream. Its internal lining is adorned with tiny finger-like projections called villi, which greatly increase its surface area for efficient absorption. Externally, the small intestine is protected by a serosa layer, depicted here in striking white. Sandwiched between these layers are the inner circular muscles and outer longitudinal muscles, represented in soft pink hues. These muscular layers work harmoniously to propel food through peristalsis - rhythmic contractions that aid in digestion. To facilitate nutrient uptake into our bloodstream, an extensive network of blood vessels is illustrated in vibrant red tones throughout the artwork. Additionally, we can observe a yellow lymphatic network responsible for absorbing fats from digested food. This mesmerizing print not only celebrates human anatomy but also serves as a reminder of how intricately designed our bodies are to perform essential functions like digestion and absorption.
