Carbohydrate Digestion00:57

Carbohydrate Digestion

122.5K
Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...

What is Monogastric Digestion?

75.3K
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.

Lipid Digestion01:06

Lipid Digestion

99.4K
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Protein Digestion01:02

Protein Digestion

111.1K
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Endoscopic Procedures III: Video Capsule Endoscopy

870
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Regulation of the Digestive System01:25

Regulation of the Digestive System

3.3K
Digestive activity regulation hinges on three primary components. Activation is prompted by a multitude of mechanical and chemical indicators, primarily detected by receptors within the stomach and intestines' walls. These receptors predominantly respond to factors such as mechanical stretching of the organ walls, changes in pH and osmolarity, and the presence of digesting materials and their by-products.
The effectors in this regulation system are glands and smooth muscles. Activation of...

    Summary

    Digestive endoscopy offers advanced therapeutic options for early gastrointestinal neoplasms. Techniques like endoscopic resection and ablation are replacing surgery for specific conditions, improving patient outcomes.

    Area of Science:

    • Gastroenterology
    • Endoscopic Surgery

    Background:

    • Digestive endoscopy has evolved from diagnostic to therapeutic interventions.
    • Therapeutic endoscopy now offers alternatives to surgery and invasive radiology for specific conditions.

    Purpose of the Study:

    • To review the therapeutic modalities of digestive endoscopy.
    • To highlight endoscopic resection and ablation for early gastrointestinal neoplasms.

    Main Methods:

    • Endoscopic resection techniques include polypectomy, mucosal resection, submucosal dissection, and transmural resection.
    • Endoscopic ablation methods include radiofrequency ablation and argon plasma coagulation.

    Main Results:

    • Endoscopic resection and ablation are effective for early-stage neoplasms without significant risk of dissemination.
