Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

1.8K
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines

88.3K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Liver Physiology01:30

Liver Physiology

3.9K
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

2.1K
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...

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

76.1K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Liver Histology01:27

Liver Histology

4.7K
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...

Summary

Alterations in gut microbiota significantly impact liver disease progression via the gut-liver axis. Targeting gut dysbiosis and increased intestinal permeability offers potential therapeutic strategies for chronic liver conditions.

Area of Science:

  • Gastroenterology and Hepatology
  • Microbiology
  • Immunology

Background:

  • Liver diseases are a major global health concern, necessitating understanding of pathogenetic mechanisms.
  • Gut microbiota alterations are increasingly recognized as key contributors to liver damage progression.
  • The gut-liver axis plays a crucial role in nutrient metabolism and immune activation, influencing liver health.

Purpose of the Study:

  • To review recent knowledge on the gut microbiota's role in chronic liver diseases.
  • To explore the gut-liver axis's influence on liver pathologies from steatosis to hepatocellular carcinoma.

Main Methods:

  • Literature review of recent studies on gut microbiota and chronic liver disease.
  • Analysis of the gut-liver axis mechanisms, including nutrient absorption and immune responses.
  • Examination of the role of intestinal permeability and dysbiosis in liver pathology.

Main Results:

  • Gut microbiota dysbiosis and increased intestinal permeability are linked to liver steatosis, cirrhosis, and hepatocellular carcinoma.
  • Pathogen-associated molecular patterns translocating via the portal vein activate immune responses contributing to liver injury.
  • The gut-liver axis influences nutrient deposition and immune receptor activation, driving liver damage.

Conclusions:

  • The gut microbiota is a critical factor in the development and progression of chronic liver diseases.
  • Interventions targeting gut dysbiosis, intestinal permeability, and associated inflammatory pathways hold therapeutic promise.
  • Modulating the gut-liver axis offers a novel strategy to reduce liver damage and prevent advanced liver disease.
