Anatomy of the Intestines01:23

Anatomy of the Intestines

86.4K
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...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

1.1K
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI)  tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.

Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.0K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Physiology of Enteric Nervous System and Gut Health

807
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...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.1K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

1.5K
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.

Area of Science:

  • Immunology
  • Microbiology
  • Gastroenterology

Background:

  • Mammalian intestines host numerous microbes essential for immune system development.
  • Intestinal immunity (innate and adaptive) interacts with symbionts to maintain homeostasis.
  • Dysbiosis results from immune system and microbial imbalance, compromising gut barrier integrity.

Purpose of the Study:

  • To review the effects of gut microbiota on intestinal adaptive immunity.
  • To explore the mechanisms underlying microbiota-immune interactions.
  • To discuss immune cell plasticity in response to the gut environment.

Main Methods:

  • Literature review of recent findings.
  • Synthesis of current research on gut microbiota and immunity.
  • Analysis of immune cell plasticity and microenvironmental influences.

Main Results:

  • Gut microbiota significantly influences the development and function of intestinal adaptive immunity.
  • Immune tolerance towards symbionts is maintained by adaptive immunity.
  • Innate immunity modulates adaptive responses to commensal bacteria.

Conclusions:

  • Maintaining a balance between the gut immune system and microbiota is vital for intestinal health.
  • Gut microbiota plays a critical role in shaping adaptive immunity and immune cell plasticity.
  • Understanding these interactions is key to addressing dysbiosis-related disorders.
