The spelling of "Eck fistula experiment" may seem confusing at first, but can be easily understood through its IPA phonetic transcription /ɛk ˈfɪstjʊlə ɪkˈspɛrɪmənt/. "Eck" is pronounced as "ek" with a short "e" sound, while "fistula" is pronounced as "fist-yuh-luh" with emphasis on the first syllable. "Experiment" is pronounced as "ik-sper-uh-muhnt". The term refers to a medical experiment that involves creating an artificial connection between an artery and a vein to study blood flow.
The term "Eck fistula experiment" refers to a scientific experiment performed by German physiologist Friedrich Wilhelm Eck in the early 20th century. Specifically, it involved the creation of a fistula, or an abnormal connection, between an artery and a vein in a living organism, usually an animal. Eck pioneered this experimental technique to study various aspects of blood circulation and to investigate the physiological effects of such arteriovenous fistulas.
In the Eck fistula experiment, an artery and a vein, usually from the same organism, are surgically connected to establish a direct, unimpeded flow of blood between the two blood vessels. This abnormal connection enables researchers to manipulate and observe the characteristics of blood flow through the created fistula.
By creating an Eck fistula, researchers can investigate different physiological phenomena, such as the changes in blood pressure and flow rate, the exchange of gases and nutrients, and the effects on surrounding tissues. This experimental technique has been particularly valuable in the study of circulatory dynamics, the regulation of blood flow, and the evaluation of vascular diseases.
The Eck fistula experiment has contributed significantly to our understanding of cardiovascular physiology and pathology. It has provided important insights into the mechanisms underlying blood circulation and the interplay between arterial and venous systems. Despite its historical context, the Eck fistula experiment remains a cornerstone in research related to blood flow and cardiovascular studies.
Shutting off the liver of an experiment animal from the portal circulation by making an anastomosis between the vena cava and portal vein and then ligating the latter close to the liver.
