The horse’s liver is a large, complex gland that plays a vital role in nutrient metabolism. It participates in the metabolism of proteins, carbohydrates, and fats; synthesizes cholesterol and bile acids; initiates bile formation; transports bilirubin; metabolizes certain drugs; and controls carbohydrate transport and storage. These functions are essential for the horse’s overall health and well-being.
What Role Does the Liver Play in a Horse’s Nutrient Metabolism?
The liver is the largest gland in the body and the most complex in function. The liver’s microscopic anatomy reveals a uniform structure of cell clusters called lobules, where the liver’s vital functions are carried out. Each lobule consists of numerous cords of rectangular liver cells, or hepatocytes, that radiate from central veins.
How Does the Liver Metabolize Protein, Carbohydrates, and Fat?
The liver participates in the metabolism of protein, carbohydrates, and fat. Hepatocytes contain many mitochondria, which provide the energy needed for the many synthetic and metabolic functions of the liver cell. The cytoplasm also contains a series of long tubules, called the endoplasmic reticulum, which provides many enzymes essential to liver function.
What is the Liver’s Role in Cholesterol and Bile Acid Synthesis?
The nonribosomal, or smooth, endoplasmic reticulum is where cytochromes (combinations of heme from hemoglobin with various proteins) and certain enzymes undertake the important hepatic functions of drug and hormonal metabolism and also cholesterol synthesis.
How Does the Liver Handle Bilirubin?
Hepatocytes also conjugate with carbohydrate components of bilirubin and other fat-soluble metabolic and foreign compounds and thereby are made soluble in water. Bilirubin is the product of hemoglobin metabolism that is formed in the bone marrow and the lymphatic tissue and is carried to the liver after becoming bound to plasma albumin. It is released at the hepatocytic sinusoidal membrane and is transported to the smooth endoplasmic reticulum, where it is conjugated with one or two molecules of glucuronic acid and thereby becomes soluble in water and excretable in bile.
What Other Functions Does the Liver Perform?
The liver also metabolizes and transports certain drugs and controls the transport and storage of carbohydrates.
