Below is information on the structure and function of the canine liver. We’ll tell you about the general structure of the liver, how the liver works in dogs, common diseases that affect the liver, and common diagnostic tests performed on dogs to assess liver function. many liver diseases begin with “hepático” which means liver. for example, “hepatopathy” means disease of the liver and “hepatitis” means inflammation of the liver.
what is the liver?
A very complex and hard-working structure, a dog’s liver is the largest organ in the body. The liver filters blood and has hundreds of other functions, most of which are necessary for life and are not performed anywhere else in the body. each part of the liver is capable of performing all its tasks, and it is the only organ in the body with this capacity. The liver has an amazing ability to recover from injury and regenerate new tissue.

where is the liver found in dogs?
The liver is a multilobed organ located in the anterior part of the abdominal cavity. it is located directly behind the diaphragm (the muscle that helps breathing and separates the chest from the abdomen) and directly in front of the stomach. the liver is placed horizontally in the front of the abdomen, with a proportionally larger part of the liver on the right side.
what is the general structure of a dog’s liver?
Normal liver is a deep red color with a firm consistency. it is divided into several different lobes, and each lobe is made up of multifaceted units called liver lobules. each lobe is composed of a curved sheet of cells enclosing numerous blood-filled cavities known as sinusoids. These sinusoids give the liver a spongy texture and allow it to retain large amounts of blood.
Two main blood vessels enter the liver: The portal vein carries most of the blood to the liver and contains nutrients from the gastrointestinal tract, as well as chemicals and medications that have been absorbed by the body. The hepatic artery carries oxygen-rich blood to the liver from the heart and lungs.
Two main conducting structures exit the liver. hepatic veins drain blood from the liver. The bile ducts carry bile from the liver cells to the gallbladder, a pear-shaped bag located below the liver.
what are the functions of the liver?
The liver regulates the levels of many different chemicals and substances in the blood and excretes bile, a yellow-green digestive fluid. all blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down nutrients, chemicals, and medications into forms that are easier for the rest of the body to use. there are over 500 vital functions associated with the liver. Some of these features include the following:
what are common liver diseases in dogs?
Because the liver is involved in many biochemical processes, many different diseases can affect it. a variety of clinical signs can be observed with liver disorders; however, in many cases, one of the first signs of illness is jaundice. Jaundice occurs when the blood contains too much bilirubin, causing the skin, gums, and whites (whites of the eyes) to turn yellow. Ascites (fluid in the abdominal cavity), another clinical sign seen with liver disease, occurs when there is impaired blood flow through the portal vein. this leads to hypertension (high blood pressure) in the portal vein, which causes fluid to leak from the portal vein into the abdomen. low levels of albumin protein in the blood due to liver disease can also cause ascites.
The liver has a remarkable ability to produce new cells to replace its own diseased or damaged cells. this regenerative ability allows the liver to return to normal function in some cases.
Some examples of liver disease include:
what types of diagnostic tests are used to evaluate the liver?
There are many diagnostic tests that are helpful in evaluating the liver.
