Abstract
Arterial bifurcations in the cardiovascular system of a rat were studied, using a resin cast of the entire arterial tree. At each bifurcation, measurements were made of the diameters of the three vessels involved, the two branching angles, and the angle delta, which the parent artery makes with the plane containing the two branches. The results were found to be consistent with those reported previously in man and monkey. In addition, measurements of delta in the present study indicate that arterial bifurcations are mostly two dimensional.
摘要
利用大鼠整个动脉树的树脂铸型，对其心血管系统中的动脉分支进行了研究。在每个分支处，测量了涉及的三根血管的直径、两个分支角度以及母动脉与包含两个分支的平面所成的δ角。结果发现与先前在人类和猴子中报道的结果一致。此外，本研究中对δ角的测量表明，动脉分支大多是二维的。
