Ⅰ. Functional properties of different blood  vessels  不同血管的功能特征 1. Artery: 动脉 A. Aorta and large artery (windkessel vessel ) 主动脉和大动脉,又称弹性贮器血管
pressure reservoir 压力储存器
maintain the continual blood fluid in the
artery system.
维持动脉系统内连续的血流
Low resistance vessel 低阻力血管
transport blood to every apparatus of the globle body
运送血液到全身各个器官
B. Middle artery: carry blood to arterioles (distribution vessel)中动脉:运送血流至小动脉,又称分配血管。
C. Small artery and arteriole — resistance vessels  小动脉和微动脉-阻力血管Small artery and arteriole are the main position anism to regulate an blood flow and the redistribution of blood among apparatus. The diameter of resistance vessels are regulated by neurohormonal factors. 小动脉和微动脉是机体调节器官血流量和器官之间血液重新分配的主要部位,其血管的口径受神经体液因素的调节。
2. Capillary vessels: exchange vessels
毛细血管:交换血管
Blood flow from arteriole to venules by passing
capillary to carry out the exchange of substances
between blood and interstitial fluid.
血流通过毛细血管从小动脉到小静脉,完成
血液和组织液的物质交换。
