[Morphologic changes of the contractile structures of the heart and walls of the major blood vessels during physical loading].
The author carried out a complex of macroscopical, histological and morphometric methods of examination of the heart, wall of the aorta, posterior caval vein and femoral artery of mature rats in conditions of experimental modelling of physical loads of various volume and intensity. It was established that the process of adaptation to physical loads consists not only of local changes occurring in the myocardial and smooth myocytes of the examined artery and vein walls but also in the formation of definite qualitative and quantitative relationships between the contractile structures of the heart and major blood vessels evidencing, thus, the importance of systemic morphofunctional transformations in the process of adaptation.
