Morphofunctional characteristics of the venous bed of the myocardium in response to acute hypoxia

Anatomical redistribution of blood outflow between the superficial and deep pathways is motivated, changes in microvessels under a circular hypoxia are presented. General peculiarities in structure of the sources for both pathways are ascertained, as well as specific differences stipulated by the physiological role of the cardiac venous sinusis.
