Artificial or Real?
The heart is in the center of the body and is the most vital organ in the body and you cannot survive without it. In the stressful environment, lots of strain is put in your heart, which leads to many heart diseases such as a heart attack, leaky valves, blocked coronary arteries causing the demand toward scientific developments to produce more developed artificial hearts and replacement of heart valves to increase.
Though out the years, science has evolved enormously and this helps the people with heart diseases, which currently affect more than 100 million people around the world. Biologists and other scientists have come up with a solution to solve the problem; they have invented artificial hearts and pacemakers to buy time for a patient to receive a real heart from a deceased ...view middle of the document...


The human body needs oxygen in order to live. The circulatory system is responsible for filtering oxygenated blood and deoxygenated blood from the body.  Blood entered the heart through two veins, the superior vena cava and the inferior vena cava. Both of these veins sent de-oxygenated blood into the right atrium, which then went to the right atrium. From there it then went to the lungs through the Pulmonary vein. Within the lungs, the deoxygenated blood becomes oxygenated, which is then sent through left atrium and left ventricle, and then blood is sent all thought out the body.
The heart can malfunction in many ways. Cardiovascular disease occurs when the heart becomes either clogged, broken down, or in need of repair. Severe cardiovascular disease is the leading cause for a need of heart transplantation, but other malfunctions such as valve damage and chamber problems also require the need for a new or artificial heart. Currently, there are 12 million people in the world who have at least one kind of cardiovascular disease. The two main causes for heart transplantation and artificial hearts in the cardiovascular disease are the coronary heart disease and congestive heart failure.
In many of the surgeries to treat the various heart diseases, lots of blood is lost and if the patient’s blood type is available in the hospital’s blood bank, artificial blood is used. What is artificial blood? It is a substitute blood. Artificial blood is designed especially for transporting oxygen and carbon dioxide throughout the body.Artificial blood is 10 times smaller than a red blood cell and is very useful in cases of blocked arteries because these blood substitutes can go places red blood cells can’t. Anyone can be given artificial blood despite an individual’s blood type. Various manufacturers have tested the blood substitute; however, it is still not safe and effective artificial blood production which is currently being sold.
Artificial blood contains Perfluorocarbon, which
