Liver Physiology

533
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Diseases of the Liver and Gallbladder

533
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Liver Regeneration

3.3K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Liver Histology01:27

Liver Histology

753
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Summary
This summary is machine-generated.

Acute liver failure, often from acetaminophen overdose, causes serious complications. While supportive care and some treatments help, liver transplantation is the only definitive cure for this critical condition.

Area of Science:

  • Hepatology
  • Critical Care Medicine
  • Transplantation

Background:

  • Acute liver failure (ALF) is a severe clinical syndrome with high mortality.
  • Acetaminophen overdose is a leading cause of ALF in many developed countries.
  • Systemic complications significantly impact patient outcomes.

Purpose of the Study:

  • To summarize the key aspects of acute liver failure management.
  • To highlight the systemic complications associated with ALF.
  • To emphasize the role of liver transplantation.

Main Methods:

  • Review of current medical literature on acute liver failure.
  • Analysis of management strategies and treatment outcomes.
  • Focus on neurocritical care and supportive measures.

Main Results:

  • ALF presents with diverse systemic issues like cerebral edema, hypotension, and kidney injury.
  • Supportive care, particularly neurocritical care, is central to management.
  • Orthotopic liver transplant is the sole definitive curative option.

Conclusions:

  • Effective management of ALF requires a multidisciplinary approach.
  • Early recognition and management of complications are crucial.
  • Liver transplantation offers the only chance for long-term survival in eligible patients.
