XY-QH3304-5 Human heart The heart anatomy model naturally large 2 parts can be unfoldedI. Model use: This model can be used as an intuitive teaching aid to teach the shape and structure of the heart and its vascular traffic during the physiological anatomy teaching in secondary schools and colleges. For students to understand the close relationship between the heart and human blood circulation II. Model structure: The model is about twice as large as the adult heart, in a diastolic state. Put on the scaffold according to the normal physiological position of the human body. Transverse incision along the root of the pulmonary artery shows the internal structure of the left atrium and the pulmonary artery and aortic semilunar valve. A diagonal incision along the atrium shows the internal structure of the left and right ventricles. The right atrium shows the upper and lower vena cava orifices, the lower vena cava valves, the coronary sinus orifices, the ovular fossa and the right atrioventricular orifices. The left atrium shows the left and right pulmonary electrostatic pulse opening and the left atrioventricular opening. Right ventricular superior ridge, tricuspid valve, arterial conus, carpal cord, papillary muscle, sarcoid and pulmonary valve; The left ventricle shows the mitral valve, chordae tendinis, papillary muscle, sarcochyma, and active valve. Indicates the atrial septum and interventricular septum. Increase the external shape of the heart and related blood vessels and branches. Coronal sulcus, anterior and posterior interventricular sulcus; It shows auriculae, myocardial fibers, vortexes, incisures, fats and arterial ligaments. Branches are used to show left and right coronary arteries; Coronary sinus and its branch; Branches of ascending aorta and aortic arch; Superior vena cava, inferior vena cava and their branches are shown. Pulmonary veins and pulmonary arteries. |
