Abstract:
The microvasculature of the rabbit right ventricle was studied by the method of vascular corrosion cast and scanning electron microscopy. In the endocardium could be seen thin and sparse capillary network i. e. subendothelial capillary network formed by the branches of the arterioles passing through myocardium. In the myocardium, arteriole and its branches distributed in certain area. Sphincters could be seen in the beginning of the arterioles. Capillaries of the papillary muscle in right ventricle were parallel to muscle bundle and were thinner and sparser than those of the papillary muscle in left ventricle. Venous system in right ventricle wall was similar in architecture to that in left ventricle, postcapillary venule joined its corresponding venule in a "turnip root" like pattern. No A-V anastomosis could be seen, yet thebesian vessels and myocardial sinusoids directly opened into ventrical chamber could be found.
