Liver Physiology01:30

Liver Physiology

4.5K
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...

Hepatic Portal System01:21

Hepatic Portal System

8.5K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Liver Regeneration01:24

Liver Regeneration

5.3K
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

11.7K
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...

Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

828
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

266
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Area of Science:

  • Hepatology
  • Neurogastroenterology
  • Metabolic Regulation

Background:

  • The liver's function and overall homeostasis are critically influenced by the hepatic nervous system.
  • Hepatic nerves play a recognized role in regulating various physiological processes within the liver.

Purpose of the Study:

  • To review and synthesize recent findings on the role of hepatic nerves in liver function and disease.
  • To highlight emerging data on neural regulation of hepatic metabolism, regeneration, and injury response.

Main Methods:

  • Literature review of studies published in the last decade focusing on hepatic innervation.
  • Analysis of experimental and clinical data investigating the impact of hepatic nerves on liver physiology and pathology.

Main Results:

  • Hepatic nerves modulate glucose and lipid metabolism, food intake, and liver regeneration.
  • Evidence suggests a role for hepatic nerves in liver disease pathogenesis.
  • Hepatic denervation shows promise in mitigating liver graft ischemia-reperfusion injury.

Conclusions:

  • Hepatic nerves exert significant, though subtle, control over key liver functions.
  • Targeting hepatic neural pathways may offer therapeutic benefits for liver diseases and transplantation.
  • Further research is essential to fully elucidate the neural pathways involved in liver response to disease.
