这是猪冠状血管的三部分形态测量数据的第三部分，给出了动脉树的完整定量描述[卡萨布等人，Am. J. Physiol.265（Heart Circ. Physiol.34）：H350-H365，1993]、毛细血管网络[卡萨布和Fung，Am. J. Physiol.267（Heart Circ. Physiol.36）：H319-H325，1994]和静脉树（本文）。它们共同为冠状动脉血流动力学提供了定量解剖学基础。冠状小静脉具有独特的形态。与冠状动脉不同，冠状动脉具有圆柱形横截面和相当恒定的每段直径，小静脉具有近似椭圆形的横截面，通常在纵向方向上呈波浪形，并且经常像手指一样会聚在手。用硅橡胶浇铸法在5个猪心上进行了测量。通过光学切片从组织学标本中获得关于较小血管的数据。从血管铸型中获得较大血管的数据。心外膜表面的弧形静脉和血管具有独特的拓扑结构。在每个订单，长轴和短轴，长度，连接矩阵，并在所有订单的窦和thebesian静脉血管串联连接的给定订单的血管的分数的血管的数量上的数据。结果表明，猪心冠状血管中的血液27.4%在动脉（> 200 μ m），37.1%在静脉（> 200 μ m），35.5%在微循环（< 200 μ m），其中89.4%在毛细血管。
This is a third part of tripartite morphometric data of the pig coronary blood vessels, giving a complete quantitative description of the arterial tree [Kassab et al., Am. J. Physiol. 265 (Heart Circ. Physiol. 34): H350-H365, 1993], capillary network [Kassab and Fung, Am. J. Physiol. 267 (Heart Circ. Physiol. 36): H319-H325, 1994], and venous tree (this article). Together they provide the quantative anatomic foundation for coronary hemodnamics. The coronary venules have a unique morphology. Unlike coronary arterioles, which have cylindrical cross sections and a fairly constant diameter in each segment, the venules have approximately elliptical cross sections, are usually wavy in the longitudinal direction, and often converge like fingers to a hand. Measurements were made with the silicone elastomer casting method on five pig hearts. Data on smaller vessels were obtained from histological specimens by optical sectioning. Data on larger vessels were obtained from vascular casts. Arcading veins and anastomoses on the epicardial surface have a unique topology. Data on the number of vessels in each order, the major and minor axes, length, connectivity matrix, and the fractions of the vessels of a given order connected in series in all orders of vessels of the sinusal and thebesian veins are presented. It is shown that of the blood in the coronary blood vessels of a pig heart 27.4% is in the arteries (> 200 mu m), 37.1% is in veins (> 200 mu m), and 35.5% is in microcirculation (< 200 mu m), of which 89.4% is in the capillaries.
