Product Description

Conduction system of heart to heart enlargement model as the basis, to the right atrium, right ventricle, left atrium, left ventricle were dissected shows its internal structure, mainly cardiac conduction system of the morphology and position of the (green).

Teaching content:

1, the sinoatrial node: located in the superior vena cava and the right auricle of epicardial deep surface junction, a spindle, through before and after the three node beam is transmitted to the atrioventricular node.

2, atrioventricular node: located in the right side of the lower part of the right side of the room, the upper part of the coronary sinus deep surface, oval.

3, Fang Shishu and its branches: from the A-V node front-end issued, down wear right fibrous trigone ventricular septal, and is divided into a left and a second beam, right bundle branch (right foot) in ventricular septal right ventricular surface of the endocardial surface deep down, every edge of meat string to anterior papillary muscle and with right ventricular heart muscle connected, left bundle branch in ventricular septal of left ventricular surface endocardial surface downward divided into left anterior fascicular and left posterior fascicular, respectively, and reached the anterior papillary muscle and the left ventricular myocardial.

Material structure: synthetic resin.

Specification: 11x11x14cm material: PVC.
