UNASSIGNED: This study describes the implications of cardiac ventricular microscopy in @entity15117 relating to its ability to dive. For this work, 11 specimens of the marine turtle species @entity15117 found dead on the coast of Rio Grande do Norte (Northeast Brazil) were used. After necropsy, fragments of the cardiac ventricular wall were fixed in 10% buffered @entity406 solution for 24  h and then subjected to routine processing for light and @entity4653 ( @entity4653 ). The ventricle in this species is formed by the epicardium, @entity1562 and endocardium. The subepicardial layer consists of highly vascularised connective tissue that emits septa to reinforce the @entity1562 surface. There is an abundant and diffuse @entity129 plexus shown by immunostaining technique. The thickness of the spongy @entity1562 and the nature of its trabeculae varied between the heart chambers. The endocardium shows no characteristic elements of the heart conduction system. The valves have a hyaline cartilage skeleton, coated by dense irregular connective tissues characterised by elastic fibres. These findings in the green turtle ventricular microscopy are related to @entity519 resistance during diving.
