Anatomy of the Intestines01:23

Anatomy of the Intestines

84.6K
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...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

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.

The Roles of Bacteria and Fungi in Plant Nutrition02:11

The Roles of Bacteria and Fungi in Plant Nutrition

45.1K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

473
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

73.4K
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.

Physiology of Enteric Nervous System and Gut Health01:05

Physiology of Enteric Nervous System and Gut Health

555
The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

  • Immunology
  • Nutritional science

Background:

  • The gut microbiota plays a critical role in host physiology, metabolism, and immunity.
  • Diet is a primary factor influencing gut microbial composition and function.
  • Emerging evidence suggests a link between gut health and lung function.

Purpose of the Study:

  • To review the current understanding of how diet influences gut microbiota.
  • To explore the gut-lung axis and its role in immune modulation.
  • To highlight the potential of diet as a non-pharmacological approach for lung disease management.

Main Methods:

  • Literature review focusing on diet, gut microbiota, and immune interactions.
  • Analysis of studies investigating the gut-lung axis in health and disease.
  • Synthesis of current knowledge on nutrient impacts on gut homeostasis and lung health.

Main Results:

  • Dietary habits profoundly shape the gut microbiota.
  • Microbial metabolites and components modulate local and systemic immune responses.
  • The gut-lung axis involves complex immune interactions influenced by diet.

Conclusions:

  • Diet is a key modifiable factor impacting the gut microbiota and lung health.
  • Understanding diet-microbiota-lung interactions is crucial for preventing and managing lung diseases.
  • Dietary interventions represent a promising complementary strategy for lung disease management.
