[The architectonics of the lymphatic networks in the sheep heart]

Lymphatic networks of the heart were studied in sheep. Principal scheme of lymphatic networks structural organization in endocardium, myocardium and epicardium of the mammals studied was established to have a series of regularities similar to those in man and animals although possessing specific peculiarities. Lymphomicrocirculatory bed of the heart is composed of interdependent lymphatic networks of endocardium, myocardium and epicardium. Endocardial and epicardial lymphatic networks are plane and single-layered, while myocardial one is spatial. All heart coats lymphatic networks are characterized with local peculiarities (different loop parameters, capillary diameter and density in some areas) which indicates varying drainage and state of metabolism in different heart region.
