Anatomy of the Intestines01:23

Anatomy of the Intestines

85.1K
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...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

912
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.

Physiology of Enteric Nervous System and Gut Health

581
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?01:50

What is Monogastric Digestion?

73.8K
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.

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

7.8K
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...

Area of Science:

  • Immunology
  • Microbiology
  • Gastroenterology

Background:

  • Immunoglobulin A (IgA) is the most abundant antibody in mucosal secretions.
  • Recent research highlights IgA's role in modulating the commensal microbiota.
  • Existing reviews cover IgA mechanisms and intestinal development.

Purpose of the Study:

  • To focus on the interaction between IgA and the microbiota.
  • To elucidate how this interaction promotes host homeostasis.
  • To explain how IgA-microbiota interactions prevent disease.

Main Methods:

  • Literature review and synthesis of recent findings.
  • Analysis of IgA's role in microbiota regulation.
  • Focus on host-microbe interactions.

Main Results:

  • IgA plays a key role in shaping the commensal microbiota composition and function.
  • The interaction between IgA and microbiota is essential for maintaining gut homeostasis.
  • Dysregulation of this interaction can lead to disease.

Conclusions:
