The walk-in and huge heart models

The walk-heart models represent the anatomical structure of the institution. They illustrate how this hollow muscle keeps the circulation going, but also show pathological changes on. Moreover, the use of implantable medical devices such as stents and artificial heart valves, and consolidates vessel bypass is a bybass indicated by the Interpretation.

The functioning of the heart is complex and not free from interference. Heart disease are on the rise. She has long been regarded as the main cause of death. By far the most common cause of death, the various heart diseases as a whole. All heart disease, if infarction, heart failure, heart attacks or other disorders of the heart can not handle itself is always a doctor must be consulted.

Representation of the anatomy of the heart

Anatomie des Herzens

The human heart

With the size of a fist and an average of 300 grams our heart is actually a pump system that supplies two separate circulations. The left heart pumps blood through the systemic circulation, the right heart through the pulmonary circulation. The two sides of the heart are separated by the interventricular Septum.

Valvular heart divide each half into an atrium and a ventricle. Between atria and ventricles, and between the chambers and the large blood vessels are the heart valves.

They act like valves, thus allowing the blood flow in one direction only. The valves between the left ventricle and the aorta (aortic valve), and between the right chamber and pulmonary artery (pulmonary valve) is also called pocket flaps. The valves between atria and chambers are the atrioventricular valves, also called mitral (left heart) and tricuspid (right heart).

Körper- und Lungenkreislauf

In systemic and pulmonary circulation there are arteries in which the blood is passed from the heart to the organs, and veins that carry blood from the body back to the heart. The blood can flow more better (arteriosclerosis) are concentrated the fewer the vessels due to deposits on the vessel walls and the more elastic it is. The pulmonary circulation begins in the right ventricle, which pumps deoxygenated blood through the pulmonary artery into the lungs. In the lungs, carbon dioxide is off and inhaled oxygen. The oxygenated blood then passes through the pulmonary vein in the left heart. Here the body cycle begins. The circulation starts in the left ventricle. It pumps oxygenated blood to our main artery, the Aorta.

In such a complex structure all the parts have to work together. Only then the heart can do its job properly. also works only a part of the heart is not right, the other cardiac and body parts are affected. From diseases different parts of the heart can be affected. You can also apply to the flap.

The coronary arteries supply the heart itself with power may be damaged. There are errors during the development and growth of the child's heart before the baby was born. Of this can be very different parts of the heart to be affected. Sometimes the heart muscle itself is weak and can not provide the necessary pump power. Coronary artery disease are probably the most well-known heart disease. Surely you also know someone who has suffered a heart attack or had undergone bypass surgery. This is an ischemic heart disease. Ischemia means a disorder of the blood stream. If "fat" (cholesterol) deposits on the walls of the coronary arteries, the central supply conduit through which blood flows to the heart itself narrows. At a certain degree of narrowing of the heart is no longer sufficiently supplied. The heart works less efficiently and are warning signs in the form of heart pain (angina). The main causes are stress, smoking, fatty foods, obesity and hypertension. Diseases of the coronary arteries are partly genetic.
