Physiology of Enteric Nervous System and Gut Health01:05

Physiology of Enteric Nervous System and Gut Health

790
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...

What is Monogastric Digestion?

74.8K
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.

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.

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...

Physiology of the Gastrointestinal System II: Digestion and Absorption

1.6K
The gastrointestinal (GI) tract, extending from the mouth to the anus, plays a pivotal role in the digestion and absorption of nutrients. This process involves both mechanical and chemical actions facilitated by various enzymes.
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.
In the stomach, a...

Area of Science:

  • Neurogastroenterology
  • Physiology
  • Central Nervous System Research

Background:

  • The brain-gut axis, a bidirectional communication system between the brain and gut, has been recognized for centuries.
  • Recent decades have seen significant advancements in understanding the neural and neurohormonal mechanisms governing this interaction.
  • Despite its common label, the brain-gut axis represents a mechanistically complex system.

Purpose of the Study:

  • To elucidate the intricate mechanisms of the brain-gut axis.
  • To explore the role of the brain-gut axis in maintaining physiological homeostasis.
  • To investigate how disruptions in the brain-gut axis contribute to pathophysiological conditions.

Main Methods:

  • Review of current neurobiological and physiological research.
  • Analysis of neurohormonal signaling pathways.
  • Examination of central nervous system interpretation of gut signals.

Main Results:

  • The brain-gut axis is crucial for coordinated physiological function.
  • Under pathological conditions, the axis can contribute to homeostatic imbalance.
  • Altered signaling within the brain-gut axis can lead to inappropriate physiological responses and symptoms.

Conclusions:

  • The brain-gut axis functions as an integrated system essential for health.
  • Pathophysiological states can arise from misinterpretation of gut signals by the central nervous system.
  • Dysfunction at any point in the brain-gut axis can impact sensation and normal bodily function.
