Features： 1、The model is approximately 2X diastolic in the adult heart. Place on the scaffold in the normal physiological position of the human body. 2、The inner structure of the right and left atria and the pulmonary arteries are shown in a transverse cut along the pulmonary artery. 3、A longitudinal oblique cut along the atrium shows the internal structure of the left and right ventricles. 4、The left and right ventricular wall of the model and the section along the pulse of the artery can be disassembled. 5、2X Life size of the model. 49 parts indicate identification, suitable for teaching use. Specification： Item Type: Heart Model Material: PVC 2X Life size of the model, showing the normal morphology of the heart, arteriovenous and valvular structure. Size: Approx. 17 x 13 x 28cm / 6.7 x 5.1 x 11.0in The model is approximately 2X diastolic in the adult heart. Place on the scaffold in the normal physiological position of the human body. The inner structure of the right and left atria and the pulmonary arteries are shown in a transverse cut along the pulmonary artery. A longitudinal oblique cut along the atrium shows the internal structure of the left and right ventricles. The right atrium showed superior, inferior vena cava orifices, inferior vena cava valve, coronary sinus orifices, ovoid fossa and right atrioventricular orifices. The right atrium shows the left and right pulmonary static veins and the left atrioventricular orifice. The right ventricle showed the superior ventricular ridge, tricuspid valve, arterial conus, carpal cord, papillary muscle, column and pulmonary artery valve. The left ventricle shows the mitral valve, chordae tendineae, papillary muscle, column, and active valve.Atrial septum and interventricular septum. Increase the external shape of the heart and the associated vessels and branches. Indicator tube status, anterior and posterior compartment grooves;Demonstrative auricle, myocardial fibers, cardiac vortexes, cardiac notch, fat and arterial ligaments, demonstrative left and right, coronary arteries and their branches; The coronary sinus and its branches are shown.Branches of the ascending aorta and aortic arch; Superior vena cava, inferior vena cava and their branches; This shows the pulmonary vein and pulmonary artery. The left and right ventricular wall of the model and the section along the pulse of the artery can be disassembled.
