Key Points

To summarize the histostructural features of the post-diaphragmatic digestive system in pigs.
Histological examination of the intestine, liver, and gallbladder.
Identification of key structural adaptations for digestion and absorption.
Assessment of immune defense mechanisms in the digestive organs.
The small intestine shows long villi and deep crypts, enhancing nutrient absorption.
The liver has defined lobules and portal triads, indicating active metabolism.
The gallbladder features mucous folds, optimizing bile storage and release.

Abstract

This paper summarizes the histostructural features of the intestine, liver and gallbladder, highlighting the adaptations that allow efficient digestion, nutrient absorption and immune defense. The small intestine has long villi, deep Lieberkühn crypts and enlarged Peyer’s patches (Young, 2020). The liver is distinguished by well-defined lobules, prominent portal triads and metabolically active hepatocytes, and the gallbladder is characterized by mucous folds that allow the storage and evacuation of bile (Trautmann & Fiebiger, 2015). These features allow the pig to efficiently digest a varied diet, with an optimal hepatic detoxification and a robust intestinal immune response. The information presented is essential for the interpretation of physiological and pathological changes induced by nutritional, toxic or microbial factors, and provides a framework for applied research in veterinary medicine and animal nutrition (Moeser, 2007).
