One of the most important internal organs is the liver. It is the most voluminous of all the viscera, weighs about 1.5 kg in men adult. It is located on the right upper quadrant of abdominal cavity, protected by the ribs. It has brownish-red color, is brittle and fragile, having a smooth surface, covered by a capsule itself.
The liver is divided into two parts (lobes). The right lobe is six times larger than the left. The body is completely covered by peritoneum and is irrigated by the hepatic artery, receiving blood venous spleen and intestines through the portal vein.
Below the right lobe is located in the gallbladder, a bag of 9 cm, about which has the ability to collect about 50 ml of bile produced by the liver.
The liver, along with the spleen and bone marrow are the organs responsible for hematopoiesis, training and development of blood cells. They are also called organs.
It participates in the process of digestion, stores vitamins, cancels the influence of drugs, stores energy, and produces compounds necessary for coagulation of blood. One can imagine that a body so important to be extremely complex, difficult to treat. The liver is also an intricate challenge for medicine. So much so that there is still no medicine that will revive the functions of a liver that has filed for bankruptcy. Once killed, the liver cells do not recover. However, it is difficult to cure a diseased liver; the incredible versatility of a healthy liver has given life expectancy at thousands of people around the world.
Liver tissue: You can lose about 75% of this tissue by disease or surgical intervention, without it stops working. Tissue of liver is composed of minute formations that are called lobes, consisting of columns of liver cells (hepatocytes), surrounded by tiny channels (canaliculated), through which passes the bile secreted by hepatocytes. These channels merge to form the hepatic duct which, together with the duct coming from the gallbladder bile forms the common bile duct, which discharges its contents in duodenum. The liver cells help the blood to absorb substances nutrients and excrete waste materials and toxins, and as steroids, estrogens and other hormones.
Liver function: -Secrete bile, which operates in the liquid emulsion of fat ingested, thus facilitating the action of lipase. -Remove glucose molecules in the blood combined them chemically to form glycogen which is stored. In moments need, glycogen is converted into glucose molecules, are re-released into the circulation. -Store iron, copper and vitamins into cells. -Synthesize several proteins present in blood, immunological factors and clotting disorders and substance carriers of oxygen and fats. -Produce carbohydrates from lipids or proteins, and lipids from carbohydrates or protein. -Downgrade alcohol and other toxic substances, assisting in detoxification of the body. -Destroy red blood cells (red) old or abnormal transforming their hemoglobin to bilirubin, the pigment brown-green present in bile. -Synthesize cholesterol and purify many drugs and other substances such as enzymes. -Controlling the balance hydro-normal saline.
Liver diseases: There are several diseases that can reach the liver. Symptoms vary depending on the severity, but some of the most common are: jaundice, fluid retention, and fatigue, tendency to bleed, muscle weakness, dark urine, nausea and vomiting, loose whitish and mental confusion.
Depending on the damage to the body by the underlying disease may changes occur in the absorption of vitamins and nutrients, accumulation of toxic substances in the body and reduce the production of proteins and other factors necessary for blood clotting.
