| The veins that carry the nutrient-charged venous blood away from the intestinal wall, after the nutrients have moved through the intestinal wall, are uniformily distributed along the length of the small intestine. From this image it is clear why bullet or knife or arrow damage to this part of the body would both lead to internal infection from material in the gut, and complex repair problems for the blood vessels. Note also that the intestinal wall is not covered with a strong protective sheath of muscle, and the connective tissue sheets are thin and fragile. Imagine a surgeon having to cut into that and then sew it back up in any kind of aseptic manner. Incidentally, this is exactly what your small intestine looks like. | ||
