Anatomy of the Gastrointestinal System01:26

Anatomy of the Gastrointestinal System

2.7K
The human digestive system is an intricate and essential network for nutrient absorption and waste elimination. It encompasses the gastrointestinal (GI) tract and several accessory organs.
Here's a detailed walkthrough of this complex system:

Impact of Groups on Groups

238
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Histology of the Gastrointestinal (GI) Tract01:20

Histology of the Gastrointestinal (GI) Tract

3.4K
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...

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

1.2K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Impact01:30

Impact

487
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Summary
This summary is machine-generated.

Gastrointestinal impactions are a significant risk for backyard poultry due to foraging behaviors. Long grasses and certain feeds can cause impactions, highlighting the need for pasture management and dietary adjustments.

Area of Science:

  • Veterinary Pathology
  • Avian Health
  • Gastroenterology

Background:

  • Backyard poultry are raised in less controlled environments than commercial poultry.
  • This increases exposure to diverse ingestible substances, including forage.
  • Gastrointestinal impactions have been observed in backyard flocks.

Purpose of the Study:

  • To determine the prevalence of gastrointestinal impactions in backyard poultry.
  • To identify common causes of these impactions.
  • To provide recommendations for prevention.

Main Methods:

  • Retrospective analysis of autopsy submissions to the California Animal Health and Food Safety laboratory system.
  • Data collected from January 2013 to July 2018.
  • Case identification based on gastrointestinal impaction.

Main Results:

  • Gastrointestinal impaction was associated with 42 backyard poultry deaths.
  • Fibrous plant material, primarily grass, caused 76% of impactions.
  • Compacted feed and miscellaneous items (plastic, wood) caused the remaining 24%.

Conclusions:

  • Foraging, particularly on long grasses, is the predominant cause of impaction in backyard poultry.
  • Long grasses pose a significant health hazard.
  • Producers should maintain short pastures, select appropriate feeds, and provide grit.
