Anatomy of the Intestines01:23

Anatomy of the Intestines

87.5K
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...

Small Intestine01:15

Small Intestine

4.0K
The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

Large Intestine01:09

Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Nerve Supply of the GI Tract01:27

Nerve Supply of the GI Tract

3.6K
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

Histology of the Gastrointestinal (GI) Tract01:20

Histology of the Gastrointestinal (GI) Tract

3.5K
The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

Histology of the Large Intestine

3.1K
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

Area of Science:

  • Microbiology
  • Animal Science
  • Gastroenterology

Background:

  • Intestinal microbiota composition varies significantly across different gut regions.
  • Understanding these variations is essential for accurate interpretation of microbiota studies in animals, particularly in meat rabbits.

Purpose of the Study:

  • To investigate the differences between cecal and fecal microbial communities in Caldes meat rabbits.
  • To determine the impact of sampling area selection on the characterization of intestinal microbiota.

Main Methods:

  • Cecal and fecal samples were collected from rabbits fed ad libitum or restricted diets.
  • Bacterial and archaeal populations were analyzed using 16S rRNA gene amplicon sequencing on the Illumina MiSeq platform.
  • QIIME software was used for operational taxonomic unit (OTU) detection, and statistical analyses (alpha-diversity, ANOVA, sPLS-DA) were employed.

Main Results:

  • No significant differences in overall microbial diversity or richness were found between cecal and fecal samples.
  • Specific bacterial genera (e.g., Clostridium, Bacteroides in cecum; Oscillospira, Coprococcus in feces) showed differential abundance.
  • Sparse partial least squares discriminant analysis (sPLS-DA) effectively identified discriminative OTUs between sampling sites.

Conclusions:

  • The choice of intestinal sampling area significantly influences the relative abundance of certain microbial taxa in rabbits.
  • Distinct microbial profiles exist between cecal and fecal environments, highlighting the importance of site-specific sampling.
  • Careful consideration of the sampling area is recommended for robust and reproducible intestinal microbiota assessments in rabbits.
