LAMBS of DAY'S AGE of V.V have FEATURES of STRUCTURE
of WALL of INTRAORGANNIKH of ARTERIES And VEINS of LIGHTS.

aspirantka* the Sonth branch of the National university of nature and
environmental of Ukraine the «Crimean agrotekhnology university»
Investigated the artery and vein of the right and left lung in daily tsigay
breed sheep. Using a complex of morphological methods, found that the main
pulmonary arteries are the arteries of elastic Tapu, and other arteries in the
arteries, smooth-muscle and muscle type.
Lambs, structure of lights, artery, vein. System of blood and
lymphokinesis, together with the nervous system provides intercommunication
between the structural components of organs, vehicles and all organism.
Analysis of the last publications. Pulmons arteries and veins which
provide intensity of motion of blood in the first minutes after birth have a
special value. The functional value of the vascular system of small circle of
circulation of blood consists in providing of interchange of gases function of
lights, while bronchial vessels satisfy own circulator-metabolic necessities of
pulmonary fabric.
Research purpose – viznachitis of pecifiku structure of walls of
intraorgannikharteriy and veins of lights for lambs of day's age.
Material and research methods. Blood vessels doslidzhuvali right and left
lights for day's lambs of cigayskoy of breed.
Research results. Set that day's lambs have pulmonary and bronchial arteries
and veins of small circle of circulation of blood and bronchial arteries of large
circle the basic source of krovopostachannya of lights. The internal shell of
internal arteries contains an endothelia, subendothelial layer from magnificent
thinly fibrylar of connecting fabric and internal elastic membrane. Arteries of
middle and shallow calibers, belong to the arteries elastically muscle and muscle
types. In the arteries of shallow caliber an internal elastic membrane is very
thin, and in the arteries of middle caliber of muscular type an elastic membrane
is expressly expressed. The middle shell of arteries is thicker in all, contains
smooth muscular cages. On the measure of diminishing of diameter of arteries
and their approaching to arteriol all shells of arteries are thinned. The amount of
elastic fibres diminishes in an external shell, an external elastic membrane
disappears. The outflow of blood from lights takes place on pulmonary and
bronchial veins which begin going on the dome of bottom of teethridges of
lights. They take blood from the networks of capillaries for both sides of
alveolar sacs and kanal'civ, also go out from the capillary network of bronchial
arteries, in arterial walls. Meeting one of odnoy, shallow veins form 7 large
venous barrels of pulmonary veins, yaks, fall in the left auricle.
Conclusion
The main arteries of large caliber belong to the arteries muscularly-elastic type,
and the arteries of small calibers belong mainly to the arteries of muscular type.
The wall of arteries of lights is formed by three shells from which major middle.
