Morphological features of the venous bed of the heart of the Baikal seal

The article describes the features of venous blood outflow from heart in Baikal seal. objects for study were corrosion preparations 11 hearts seal aged 1 month to 10 years. In our research we used methods preparation, filling vessels with use "Kudo" mounting foam, photographing and sketching branching vessels. It was established that seal, occurs through prominent coronary sinus large, intermediate, oblique vein left atrium, middle right veins flow into it. 18.2% hearts, a valve found at border great sinus. begins above apices is formed fusing 6-11 collateral wall ventricle, pericardial plexus, 9-16 branches on side ventricle. most variable intermediate (marginal) branch, which cases has only one however, there are two ones or 9.1% cases, common trunk. located sub-sinus sulcus anastomoses branch heart, have 5-6 branches, among marginal prominent. 27.3% seals fusion veins, as well duct connecting large cardiac this
