Detailed anatomical studies of the circulatory system of this species remain scarce. The aim of this study was to describe the heart, major blood vessels, and coelomic circulation in this species. Four male and two female cadavers were received from environmental authorities, preserved with soft embalming techniques and injected with latex injection. The sinus venosus, positioned dorsally, lacked internal septa and drained into the right atrium via a bicuspid sinoatrial valve. The ventricular sub chambers\u2014\n                    <jats:italic>cavum arteriosum, cavum venosum, and cavum pulmonale<\/jats:italic>\n                    \u2014demonstrated a spatial distribution distinct from other squamates, with the\n                    <jats:italic>cavum arteriosum<\/jats:italic>\n                    and\n                    <jats:italic>cavum venosum<\/jats:italic>\n                    predominantly occupying the left side of the heart. A muscular crest within the ventricle facilitated additional separation between oxygenated and deoxygenated blood, enhancing circulatory efficiency. The aortic and pulmonary trunk valves were identified as simple bicuspid structures. The right aortic arch originated both carotid trunks. The aorta originated multiple parietal, mesenteric, and renal arteries, exhibiting inter\u2010individual variability. A remarkable vascular plexus at the duodenal bulb was observed, from which the hepatic artery originated. The ventral abdominal vein connected the pelvic region to the hepatic portal system. The absence of lateral abdominal veins supports the recommendation to avoid drug administration in the pelvic limbs and tail to prevent renal or hepatic first\u2010pass effects. These findings provide essential information for clinical applications, including surgical interventions and diagnostic imaging in reptile medicine.\n                  <\/jats:p>","DOI":"10.1111\/ahe.70081","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T07:11:30Z","timestamp":1767165090000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Cardiovascular Anatomy of the Green Iguana (\n                    <i>Iguana iguana<\/i>\n                    ): Heart Structure, Major Vessels, and Coelomic Circulation"],"prefix":"10.1111","volume":"55","author":[{"given":"Nathalia","family":"Correa\u2010Vargas","sequence":"first","affiliation":[{"name":"Grupo de Investigaci\u00f3n CIBAV, Escuela de Medicina Veterinaria, Facultad de Ciencias Agrarias Universidad de Antioquia UdeA  Medell\u00edn Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Arcila\u2010Lopera","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n CIBAV, Escuela de Medicina Veterinaria, Facultad de Ciencias Agrarias Universidad de Antioquia UdeA  Medell\u00edn Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9s","family":"Sep\u00falveda\u2010V\u00e1squez","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n CIBAV, Escuela de Medicina Veterinaria, Facultad de Ciencias Agrarias Universidad de Antioquia UdeA  Medell\u00edn Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1751-3198","authenticated-orcid":false,"given":"Lynda","family":"Tamayo\u2010Arango","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n CIBAV, Escuela de Medicina Veterinaria, Facultad de Ciencias Agrarias Universidad de Antioquia UdeA  Medell\u00edn Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"issue":"1","key":"e_1_2_9_2_1","first-page":"11","article-title":"Laboratory Reptile Surgery: Principles and Techniques","volume":"50","author":"Alworth L.
