This plastinated specimen corresponds to the porcine large intestine, showing the caecum associated with the ascending colon arranged as a spiral colon (colon ascendens spiralis). The characteristic conical spiral configuration is evident, with clearly defined centripetal and centrifugal coils connected by a central flexure. The external surface shows marked sacculations (haustra coli) produced by the arrangement of the taeniae coli, which are typical in the pig. The mesocolon is visible centrally, anchoring the coils and converging toward the root of the spiral, allowing appreciation of the three-dimensional organization of the ascending colon in this species.

• The species-specific anatomy of the porcine ascending colon, particularly the spiral organization that differentiates it from the colon of carnivores.
• The relationship between taeniae coli and haustration, explaining the segmented external appearance of the porcine colon.
• The spatial arrangement of the caecum and ascending colon, which is essential for understanding intestinal transit and fermentation in pigs.

• To teach comparative anatomy of the large intestine, highlighting differences between monogastric species.
• To support clinical teaching related to colonic torsions, obstructions, or surgical approaches by visualizing the spiral arrangement and mesenteric attachments.
• To help students orient themselves anatomically during necropsy or abdominal surgery by recognizing normal topography of the porcine caecum and ascending colon.
