| description | This study has been developed in order to describe the anatomy of the heart of Guinea pig (Cavia porcellus [Linnaeu,1758]) fetuses in late gestation and to obtain anatomical characteristics that can support and help the understanding of the physiology of fetal circulation. Fetuses have been collected from three female in late gestation, which were described and photographed macroscopically, trhough light microscopy in HE and scanning electronic microscopy. The fetal heart is divided into four cavities, it is surrounded by the pericardium, and it has three layers: epicardium, myocardium, and endocardium. Foramen ovale has a great importance in the fetal circulation, but it could not be visualized in sections carried out in this study. Through these results we conclude that the hearts of Guinea pig fetuses differ from those of other species in structures such as the cranial vena cava, which is not divided into left and right, and that the walls thickness of left and right ventricles does not differ significantly. |
