Abstract: The research elucidated the histological and morphological characteristics of the esophagus during adulthood. A selection of fifteen healthy guinea pigs was obtained from the public market for this study. The animals were euthanized using ketamine at a dosage of 30 ml/kg body weight via intramuscular injection. The esophagus was examined topographically in situ. Morphologically, the esophagus is a muscular tube divided into three segments: cervical, thoracic, and abdominal. It extends from the oropharynx to the cardiac region of the stomach, where it connects at the distal end. Histological analysis revealed that the esophagus comprises four layers: mucosa, submucosa, muscularis, and adventitia or serosa, and it lacks glandular structures. This study enhances the understanding of both the gross and microscopic morphometrics of the esophagus in guinea pigs.
