„Erler-Zimmer GmbH & Co. KG human circulatory system model:

Model G28: Detailed, life-size model showing all major structures of the placenta in true color. Placental divisions and abdomen and chorionic membranes on the fetal surface are depicted in the placenta. Shows cord vessels through the umbilical membrane. A cut into the placenta reveals the subchorial space, villi with fetal arteries and veins, decidual septa, spiral arterioles, and marginal sinus. With key card.
Model G29: One-piece, semi-schematic model depicting the fetal heart, lungs, liver, placenta and cord, aorta and vena cava in special colors and marked to show blood circulation and direction of blood flow. Mounted on a cushion: 27 x 44 cm.
Model G142: An important tool for understanding the difference in artery and vein histology. This one-piece model shows one artery and two veins in great detail. One vein is cut longitudinally to show closed and open venous valves; the artery and right vein are sectioned transversely so that the different layers such as the tunica media, elastic membrane and tunica adventitia are easily identified. Mounted on a cushion. Size: 20 x 30 x 27 cm. Weight: 0.8 kg.
Model G165: Enlarged 2000 times, this model shows various blood cells, including red blood cells; white blood cells (lymphocytes, monocytes, neutrophils, eosinophils and basophils); and platelets. Mounted on a board. Size: 53 x 38 x 6.5 cm. Weight: approx. 2.7 kg.
Model G230: Overview of the human circulatory system. A great opportunity to explain and understand the circulation of blood in the human body. The model clearly shows the pulmonary circulation, the heart with its chambers, atria and valves, the great vessels and the circulation to the limbs. Of course, the liver, kidneys, spleen and part of the intestine are depicted. The anterior wall of the heart can be removed. To find the vessels, the model shows the skeleton, allowing you to understand the three-dimensional paths of the vessels. Mounted on a base board, also suitable for hanging. Size: 90 x 35 x 5 cm.
Model G240: Longitudinal diameter of an artery with narrowing caused by plaque adsorption. Four transverse cross-sections show the stages of plaque construction on the arterial wall. Size: 14 x 18 x 13 cm. Weight: 0.4 kg.
Model G241: Longitudinal diameter of the artery with narrowing caused by plaque adsorption and occlusion caused by thrombus. Size: 10 x 4 x 4 cm. Weight: 0.1 kg.
Model G265: Artery cross-section model, showing 4 different stages of arteriosclerosis. The model demonstrates narrowing of the artery due to fat accumulation (cholesterol) and plaque formation. The artery model is simulated just like a real artery. Starting from a normal artery, which is a soft material, to a blockage, which is a hard material. The artery model has 4 sections shown: healthy (soft), stage 1 (medium soft), stage 2 (medium hard), stage 3 (hard). The narrowing restricts the flow of oxygen-rich blood to parts of the body and can cause blockage by a thrombus. The stages are mounted for rotation. The model is movable and cannot be disassembled. Size: 13 x 5 x 4 cm.
Model V103: This life-size model consists of 5 parts, including 2 parts of the heart, which provide a view of the internal chambers and valves. Removal of the sternum and thymus reveals the pericardial sac and major pulmonary and systemic vessels. The trachea and esophagus enter the mediastinum through the superior thoracic opening; the inferior thoracic opening is defined by the diaphragmatic muscles. Mounted on a base. Size: 40 x 26 x 30 cm.
