Examples of intestinal flora in the following topics:

  • Elimination

    • After food passes through the small intestine, the undigested food material enters the colon, where most of the water is reabsorbed.
    • Recall that the colon is also home to the microflora called "intestinal flora" that aid in the digestion process .
  • Digestive Processes of the Large Intestine

    • In the large intestine, a host of microorganisms known as "gut flora" help digest remaining food matter and create vitamins.
    • The large intestine takes about 16 hours to finish up the remaining processes of the digestive system .
    • Gut flora consists of microorganisms that live in the digestive tracts of animals and is the largest reservoir of human flora.
    • The human body, which consists of about 10 trillion cells, carries about ten times as many microorganisms in the intestines.
    • Summarize the digestive processes of the gut flora of the large intestine
  • Absorption and Feces Formation in the Large Intestine

    • The large intestine absorbs water from the chyme and stores feces until they can be defecated.
    • After the food has been passed through the small intestine, it enters the large intestine.
    • Within the large intestine, digestion is retained long enough to allow fermentation via gut bacteria, which break down some of the substances that remain after processing in the small intestine.
    • Intestinal flora are also essential in the development of certain tissues, including the cecum and lymphatics.
    • Describe the process of absorption and feces formation in the large intestine
  • Innate Resistance

    • There is good evidence that re-introduction of probiotic flora, such as pure cultures of the lactobacilli normally found in unpasteurized yogurt, helps restore a healthy balance of microbial populations in intestinal infections in children and encouraging preliminary data in studies on bacterial gastroenteritis and inflammatory bowel diseases.
    • In this context, gut is synonymous with intestinal, and flora with microbiota and microflora, the word microbiome is also in use.
    • The gut flora is the human flora of microorganisms that normally live in the digestive tract and can perform a number of useful functions for their hosts.
    • It is the largest reservoir of human flora.
    • In this context, gut is synonymous with intestinal, and flora with microbiota and microflora.
  • Digestive System: Small and Large Intestines

    • Nutrients are absorbed in the small intestine and waste is prepared for elimination in the large intestine.
    • The ileum is the last part of the small intestine.
    • The human large intestine is much smaller in length than the small intestine, but larger in diameter.
    • The colon, home to many bacteria or "intestinal flora" that aid in the digestive processes, can be divided into four regions: the ascending colon, the transverse colon, the descending colon, and the sigmoid colon.
    • The rectum is the terminal end of the large intestine.
  • Lactose Intolerance

    • Secondary, acquired, or transient lactase deficiency is caused by an injury to the small intestine, usually during infancy, from acute gastroenteritis, diarrhea, chemotherapy, intestinal parasites, or other environmental causes.
    • Lactose cannot be directly absorbed through the wall of the small intestine into the bloodstream so, in the absence of lactase, it passes intact into the colon.
    • To assess lactose intolerance, intestinal function is challenged by ingesting more dairy products than can be readily digested.
    • This might be caused by slow intestinal transit and intestinal flora changes during pregnancy.
  • Normal Gastrointestinal Microbiota

    • Gut flora consist of microorganisms that live in the digestive tracts of animals and are the largest reservoir of human flora.
    • Gut flora consists of microorganisms that live in the digestive tracts of animals and is the largest reservoir of human flora .
    • In this context, gut is synonymous with intestinal, and flora with microbiota and microflora; the word microbiome is also in use.
    • The human body, consisting of about 10 trillion cells, carries about ten times as many microorganisms in the intestines.
    • In 2009, scientists from INRA (France) highlighted the existence of a small number of species shared by all individuals constituting the human intestinal microbiota phylogenetic core.
  • Suppression and Alteration of Microbiota by Antimicrobials

    • The gut flora in the human intestinal system has hundreds of species of microbes and over 100 trillion individual microbes; in comparison, the human body has around 10 trillion cells .
    • An example is gut flora getting into the body's blood stream.
    • In the case of the gut flora, this may impair the ability of a patient to properly metabolize food.
    • If advantageous bacteria do not repopulate the intestine, this can lead to serious malnutrition problems.
    • The oblong structures are Escherichia coli (E. coli), a symbiotic bacteria found in the human intestinal system.
  • Bacterial Flora

    • The large intestine absorbs some of the products formed by the bacteria inhabiting this region.
    • The normal flora is also essential in the development of certain tissues, including the cecum and lymphatics.
    • Bacterial flora is also involved in the production of cross-reactive antibodies.
    • These are antibodies produced by the immune system against the normal flora, that are also effective against related pathogens, thereby preventing infection or invasion.
    • A mucus layer protects the large intestine from attacks from colonic commensal bacteria.
  • Overview of Human-Microbial Reactions

    • Gut flora consists of microorganisms that live in the digestive tracts of animals and is the largest reservoir of human flora.
    • The human body, consisting of about 10 trillion cells, carries about ten times as many microorganisms in the intestines.
    • Bacteria make up most of the flora in the colon and up to 60% of the dry mass of feces.
    • Fungi and protozoa also make up a part of the gut flora, but little is known about their activities.
    • Skin flora are usually non-pathogenic and either commensal or mutualistic.
