Heart and the distal trachea, carina and primary bronchi
This 3D printed specimen demonstrates the external anatomy of the heart alongside the distal trachea, carina, and primary bronchi in the posterior mediastinum. The relationship of these structures to the great vessels and left atrium is clearly shown, with the pericardial reflections marking the transverse and oblique pericardial sinuses.Heart Chambers and ValvesAn anterior window has been dissected into the right atrium and base of the auricle, exposing the right atrioventricular (tricuspid) valve and passage into the right ventricle. The pulmonary trunk has been removed to reveal the open pulmonary semilunar valves. Coronary Arteries and SinusBoth right and left coronary arteries with their named branches are visible. The posterior interventricular artery arises from the right coronary, while the circumflex artery is displayed in the coronary groove via a sectioned left auricle. The coronary sinus is retained inferior to the left atrium, although other cardiac veins have been removed. Great VesselsThe arch of the aorta is intact, showing the origins of the brachiocephalic trunk, left common carotid, and left subclavian artery. Adjacent to the aorta, the termination of the left and right brachiocephalic veins and azygos vein into the superior vena cava is preserved, illustrating the venous return to the heart.
Heart internal structures
This 3D printed heart displays the internal structures of all chambers. The superior and inferior vena cava enter the right atrium, revealing the pectinate muscles of the auricle and the nearly translucent fossa ovalis.Right Atrium and VentricleThe right atrioventricular (tricuspid) valve with its three cusps is exposed, along with chordae tendineae and papillary muscles. The conus arteriosus leads to the pulmonary semilunar valve, and the right coronary artery continues posteriorly to the posterior interventricular artery. Left Atrium and VentricleThe pulmonary veins enter the left atrium, and the left atrioventricular (mitral) valve with associated chordae and papillary muscles is visible. The left ventricle shows well-developed trabeculae carneae, and the aortic semilunar valve sits at the base of the aorta. Coronary ArteriesThe left coronary artery gives rise to the left anterior descending, diagonal, ramus intermedius, and circumflex branches. The circumflex passes near the coronary sinus, while the left anterior descending penetrates the myocardium and emerges near the apex.
Heart
This 3D print preserves the superficial anatomy of an isolated human heart along with the bases of the great vessels. All four chambers—atria and ventricles—are clearly visible, with pericardial reflections on the left atrium marking the positions of the transverse and oblique pericardial sinuses.Coronary Arteries and VeinsThe right marginal branch of the right coronary artery is visible exiting the fat-filled coronary sulcus, along with the posterior interventricular (posterior descending) artery within its sulcus. On the anterior side, the anterior interventricular (left anterior descending) artery and diagonal branches from the left coronary artery are clearly displayed. The terminal portion of the circumflex branch can be seen deep to the left auricle, alongside the great cardiac vein. On the posterior aspect, the coronary sinus collects all cardiac veins—great, middle, and small—and includes a prominent posterior vein of the left ventricle. Heart ValvesAt the bases of the ascending aorta and pulmonary trunk, the aortic and pulmonary semilunar valves are visible, providing a detailed view of the outflow pathways from the ventricles.
Bowel - Portion of Ileum
This 3D printed small loop of ileum highlights the arterial arcades in the mesentery. It demonstrates many short vasa rectae and a higher number of arcades compared to the jejunum. The mesentery is dissected to reveal the vessels and one or two large lymph nodes near the root of the mesentery. Mesenteric Fat and VesselsThe model clearly shows the fat in the mesentery extending up to and beyond the mesenteric border of the bowel, emphasizing the anatomical relationship between fat, vessels, and lymph nodes. Ileal MucosaA small segment of the ileum has been opened to display the mucosal folds, which are fewer but larger than those found in the jejunum, giving a detailed view of the bowel’s internal structure.
Bowel - Portion of Jejenum
This 3D printed small loop of jejunum illustrates the arterial arcades in the mesentery, featuring many long straight vasa rectae and fewer vascular arcades compared to the ileum. The mesentery has been dissected to reveal the fat and visceral peritoneum, along with lymph nodes (grey-light green), which are prominent near the root of the mesentery and larger vessels. Mesenteric Fat and VesselsTypically, the fat in the jejunal mesentery does not extend to the mesenteric border, allowing a clear view of the long straight vessels. In this specimen, however, a patient with a larger amount of abdominal fat shows fat extending further toward the mesenteric border, partially obscuring this window. Jejunal MucosaA small segment of the jejunum has been opened to display the mucosal folds, which are more numerous and smaller than in the ileum, providing a detailed view of the internal structure of the bowel.
Bronchial Tree
This 3D printed specimen preserves a human trachea, carina, and complete right and left bronchial trees down to the level of the tertiary lobar bronchi. Each set of lobar bronchi has been colour-coded to clearly demonstrate the bronchopulmonary segments of the right and left lung lobes.Right Lung Bronchial AnatomyFrom the right primary bronchus, the secondary bronchus to the upper lobe branches into tertiary bronchi supplying the apical (yellow), anterior (brown), and posterior (sienna) segments. The bronchus intermedius divides to supply the middle lobe, including the lateral (lilac) and medial (tan) segments. The lower lobe bronchus gives rise to the tertiary bronchi of the superior (yellow) and basal segments, which include anterior (purple), posterior (sienna), lateral (brown), and medial (tan). Left Lung Bronchial AnatomyFrom the left primary bronchus, the secondary bronchus to the upper lobe gives rise to tertiary bronchi supplying the apical-posterior (sienna), anterior (brown), superior lingual (tan), and inferior lingual (lilac) segments. The lower lobe bronchus divides into tertiary bronchi for the superior (yellow) and basal segments, including anteromedial (brown), lateral (tan), and posterior (sienna).
Human body replicas to improve teaching!
Erler-Zimmer's groundbreaking Anatomy Series features a unique and unrivalled collection of colourised human body replicas specifically designed to enhance teaching and learning. This premium collection of highly accurate human anatomy has been created directly from radiological data or real specimens using the latest imaging techniques. The 3D Human Anatomy Series offers a cost-effective way to meet your specific teaching and demonstration needs across the curriculum in medicine, health sciences and biology. A detailed description of the anatomy represented in each 3D printed specimen is included. What are the advantages of the Monash 3D Anatomy Series compared to plastic models or real human plastinates?
Each body replica has been carefully developed from selected radiological patient data or dissected human bodies of the highest quality, chosen by a highly skilled team of anatomists at Monash University's Human Anatomy Teaching Centre, to represent clinically important areas of anatomy in a quality and detail not possible with conventional models - it is real anatomy, not stylised. Each body replica has been rigorously checked by the highly qualified team of anatomists at Monash University's Human Anatomy Teaching Centre to ensure the anatomical accuracy of the final product. The body replicas are not real human tissue and are therefore not subject to any restrictions on transport, import or use in educational institutions that do not have permission to use cadavers. The
exclusive 3D Anatomy Series avoids these and other ethical issues that arise when dealing with plastinated human remains.
