Paravasal Connective Tissue Parameters Vs. Morpho-Functional Indicators In The Intraorgan Blood Vessels Of The Younger Men Lungs

Abstract

Objective — The objective of this research was to identify correlations between the paravasal components connective tissue of the blood vessels of lungs and their morpho-functional parameters. Material and Methods — In order to determine the structure of the paravasal connective tissue, the histotopographic and histological examination of lung preparations of 20 men corpses of the first mature age period was held, to determine the capacity and capacitive characteristics of the vascular bed, the determination of the Kernogan index (IK) and the veno-arterial index (VAI) were carried out. Results — It was ascertained that in the structure of the paravasal connective tissue two layers could be conditionally distinguished – the "central" and "peripheral", differing in the architectonics of the fibrous component, the nature of interaction with nearby anatomical structures. It was also revealed that infrared venous vessels IK was expressed in a greater degree in comparison with arterial. When determining VAI vascular, the channel revealed that the area of venous vessels prevailed over the arterial area. Besides, the clear correlation relationships of the structural elements of the paravasal connective tissues were investigated with arterial and venous vessel capacity values and their capacitive characteristics. Conclusion — The presence of correlation relationships confirmed a clear interaction between structural organization of the paravasal connective tissue and the functional activity of the blood vessels, providing optimal hemodynamic conditions in the organ.
