NR507 Edapt Week 5 Liver Cirrhosis Introduction to Liver Cirrhosis 91440049959 Cirrhosis of the liver is a condition characterized by the progressive scarring of liver tissue, typically resulting from long-term liver inflammation and injury. This scarring can lead to impaired liver function and potentially serious complications. Chronic liver diseases such as hepatitis C, hepatitis B, and long- term alcohol abuse are common causes of cirrhosis. 944958104141 The liver is involved in the metabolism of carbohydrates, proteins, and fats; detoxification of harmful substances; storage of vitamins, minerals, and glycogen; production of bile for digestion; and filtration of blood. Insulin is produced by the pancreas. Bile is stored in the gallbladder. Liver damage often begins with injury to hepatocytes, the liver cells responsible for various metabolic functions. This injury triggers an inflammatory response, leading to the accumulation of immune cells and cytokines in the liver. Chronic inflammation can then stimulate the activation of hepatic stellate cells, which are responsible for producing collagen and other extracellular matrix proteins, leading to the development of fibrosis. If the underlying cause of liver damage persists, fibrosis can progress to cirrhosis, characterized by extensive scarring and disruption of liver architecture. Enlargement of the liver is common in chronic liver disease, including cirrhosis, and may be palpable on physical examination. Accumulation of fluid in the abdominal cavity is a common complication of liver cirrhosis and can be assessed through physical examination and imaging studies. Enlargement of breast tissue in males can occur due to hormonal imbalances associated with liver dysfunction. Gastrointestinal bleeding, particularly from esophageal varices, is a serious complication of liver cirrhosis and can manifest as bloody or tarry stools (melena). While hypertension can be associated with chronic liver disease, it is not typically a direct consequence of liver cirrhosis. It may be more related to other comorbidities or underlying causes of liver disease, such as obesity or alcohol misuse. Normal Physiology of the Liver Physiology of the Liver Metabolism: The liver metabolizes carbohydrates, fats, and proteins, converting them into energy or storing them for later use. It also converts ammonia, a byproduct of protein metabolism, into urea, which is excreted in urine. Detoxification: The liver detoxifies substances such as drugs, alcohol, and metabolic waste products. It breaks down these substances into less harmful forms that can be excreted by the body. Synthesis: The liver synthesizes proteins like albumin, which helps maintain osmotic pressure in the blood, and clotting factors like fibrinogen and prothrombin, which are necessary for blood coagulation. Storage: The liver stores important nutrients such as glucose, vitamins A, D, K, and B-12, and minerals such as iron and copper. Immune function: Kupffer cells in the liver are part of the immune system, which help to remove bacteria and other pathogens from the blood. Bile production: The liver produces bile, a substance that helps in the digestion and absorption of fats in the small intestine. Blood filtration: The liver receives blood from the hepatic portal vein, which carries nutrients from the digestive system, and the
