　　Objective: Through the anatomical study of the tail blood vessels of experimental rats, to further clarify the pathway and distribution of arteries and veins, deepen the understanding of their physiological functions, provide anatomical basis for the standardization of animal experimental technology, and design experimental animals model?

　　Method: Infuse red and blue pigments into the tail vessels of adult SD rats and dissected them. Can formaldehyde perfusion fix the physiological pressure of the abdominal aorta and cut it into tail tissue? Can these three arterial microangiography methods mutually confirm each other?

　　Result: Did you identify three sets of longitudinal arteriovenous systems on the surface of the rat's tail, reveal the structure of the dorsal arteriovenous chain, and fill the gap in the distribution of deep blood vessels? Are the proposed distribution characteristics of arteriovenous vessels and their physiological basis inconsistent, indicating that the tail vessels have a double-cage connection structure?

　　Conclusion: This study accurately reveals the rich vascular structure of the rat tail, reveals the deep existence of the rat tail vascular system, and proposes the concept of double-frame vascular structure for discussion. We are carrying out related research on physiological functions. Do you want to avoid big losses? Does the ischemic compensatory response of the hind limbs lay a good foundation?
