Microvascular architecture of the rabbit heart was studied with scanning electron microscopy of corrosion casts. Arterioles divide into several finer branches and form a capillary plexus. Capillaries of the plexus run generally in parallel with cardiac muscle fibers and converge into venules and veins. Most of the veins run towards the epicardium, while some of them run towards the endocardium. The subendocardial veins sometimes open into the right ventricular cavity. Arterial branches of the right ventricular free wall and the right ventricular side of the septum open into the ventricular cavity. Arteriovenous anastomoses are observed in the left ventricular free wall and in the right ventricular side of the septum.
采用铸型扫描电子显微镜对兔心脏的微血管结构进行了研究。微动脉分成几个更细的分支并形成毛细血管丛。丛中的毛细血管通常与心肌纤维平行走行，并汇入小静脉和静脉。大多数静脉朝向心外膜走行，而其中一些朝向心内膜走行。心内膜下静脉有时开口于右心室腔。右心室游离壁和室间隔右侧的动脉分支开口于心室腔。在左心室游离壁和室间隔右侧观察到动静脉吻合。
