The walk-in heart model
The walk-in heart model shows the schematic representation of the most important details of our heart. Of a physician team and places, like this hollow muscle the Blutkreislauf was developed on holds, move which nutrients, hormones, water and oxygen by our body.
Why an walk-in heart model?
The work of the heart is not free from disturbances. The heart illnesses increase ever more. For a long time they are main cause of death. The different heart illnesses in their whole represent probably the cause of death most frequent with distance. All heart illnesses whether infarct, heart myasthenia, heart accumulations or other disturbances of the heart one cannot treat. Always a physician must be consulted.
Representation of the anatomy of the heart
The human heart
The heart has about the size of a fist and weighs on the average 300 gram. Strictly taken our heart consists of two pumps, which supply two separate blood cycles: The left heart pumps blood by the body cycle, the right heart by the lung cycle. The two heart halves are separated by the heart septum.
Heart valves divide each heart half into a forecourt and a Herzkammer. Between forecourts and chambers as well as between the chambers and the large blood vessels are the heart valves.
They work like valves and permit flow of blood only in a direction. One calls the flaps between left Herzkammer and Aorta (Aortenklappe), as well as between right chamber and lung artery (Pulmonalisklappe) also pocket flaps. The flaps between atria and - chambers are the sail flaps, also Mitral (left heart) and Trikuspidalklappe (right heart)
called.
In the body and lung cycle there are to Arterien, in which the blood is led of heart to the organs, and Venen, which transport the blood from the body back to the heart. The blood can flow thereby the better, the less the containers by deposits at the Gefäßwänden (Arteriosklerose) restrict and the more flexible it is.
The lung cycle begins in the right Herzkammer, which pumps oxygen-poor blood over the Lungenarterie to the lung. In the lung carbon dioxide out and oxygen is inhaled. The blood enriched with oxygen arrives then over the Lungenvene into the left heart. Here the body cycle begins. The body cycle starts in the left Herzkammer. It pumps oxygen-rich blood to our main artery, the Aorta. The body cycle is called also large cycle, because it supplies our entire body of the brain over entrails up to the skin and the muscles with blood.
In such a complex structure like the heart all parts must regularly co-operate, so that the heart can settle its task. Functioned only one part of the heart not correctly, other the parts of the body and heart are pulled in. Of diseases different parts of the heart can be concerned. They can concern also the flaps.
The Koronararterien, which supplies the heart with energy, can be damaged. There are errors during the development and the growth of the childlike heart, before the baby was born. Of it very different parts of the heart can be concerned. Sometimes will the heart muscle weak and cannot the necessary pumping performance furnish. Illnesses of the Koronararterien are probably the most well-known heart diseases.
Surely you know also someone, which suffered a cardiac infarct or a bypass operation to undergo had. It concerns an ischemic heart craneness here. Ischämie means a disturbance of the bloodstream. If “fat” (Cholesterol) settles at the walls of the heart wreath/ring containers, the central supply line narrows itself, by the blood into the heart flows. Starting from a certain degree of the narrowing the heart is no longer sufficiently supplied. The heart works less efficiently and gives alarm flags in the form of heart pain (angina). The most important causes are stress, smoking, fat meal, predominance and hypertension. Illnesses of the heart wreath/ring containers are partly also genetically conditioned.
