According to the U.S. Department of Veterans Affairs, the liver is one of the only organs in the human body capable of replacing damaged tissue. This repair can be slowed or prevented by infection or by drug or alcohol abuse.
The liver functions as a filter for the blood and also stores useful nutrients to be released into the bloodstream when needed. When the liver fails to repair itself, the resulting scar tissue can eventually become cirrhosis, according to Addiction and Recovery. As the human body contains, on average, 30 percent more liver tissue than is needed, some patients with permanent liver damage can still lead normal lives.Learn More

A heterogeneous liver appears to have different masses or structures inside it when imaged via ultrasound. These masses may be benign genetic differences or a result of liver disease. In most cases, a finding of heterogeneous liver is followed by further medical testing to determine the cause of the heterogeneity.Full Answer >
The Everett Clinic explains that “echogenic livers” are those that return stronger than usual responses to the sound waves emitted by the ultrasound machine. Ultrasound machines work by sending a harmless series of sound waves into the patient’s body. A computer inside the machine measures the echo of these waves and displays the results visually. The strength of the echo primarily varies based on the density of the object.Full Answer >
