Key Difference – VeinVS VENULE

静脉是血管，将血液载为heart。它总是很低血压。Except thepulmonary和脐静脉，所有其余的静脉都带有脱氧血液。相反，动脉carry blood away from the heart. The veins have valves in them to prevent the black flow of blood and to maintain unidirectional blood flow. They are less muscular, larger and are located closer to the skin. Venules are very smaller veins. They are the ones that collect blood from the毛细血管。收集的血液将被引导到大和中静脉，在该静脉中再次将血液转移到心脏。许多静脉会团结起来形成更大的静脉。关键区别between Vein and Venule is，静脉是一种较大的血管，可将血液传递到心脏，而该静脉是一种较小的分钟血管，可将血液从毛细血管中排出。

什么是静脉?

静脉是整个体内存在的较大血管。静脉的主要功能是将贫血的血液带回心脏。静脉分为某些类别，例如浅表静脉，肺静脉，深静脉，穿孔静脉，交流静脉和系统静脉。静脉的壁比动脉壁更薄且弹性少。静脉的壁构成了三层组织，这些组织称为Tunica Externa，Tunica Media和Tunica Intima。静脉还具有较大和不规则的管腔。

静脉是低血压血管。静脉有许多瓣膜，以防止血液流向毛细血管。这些瓣膜保持单向血液向心脏的流动。静脉是半透明in nature. The subcutaneous fat absorbs low-frequency light allowing only the highly energetic blue wavelength to penetrate through dark veins.Hence, they are blue in color due to the subcutaneous fat that they possess.

当静脉从血液中排出并从特定生物体中取出时，它看起来是灰白色的。诸如静脉功能不全的疾病，deep vein thrombosis和门户高血压与缺陷静脉有关。Ultrasound双链超声技术可用于观察静脉。静脉含有大部分血液，约占人体总血液含量的60％。

什么是电静脉？

The venules are very small blood vessels that are involved in the micro blood circulation in the body. They drain blood from the capillaries to the larger blood vessels like veins. Venules are 7 µm to 1 mm in diameter. Venules contain 25 % of the blood from the total blood content of the body. Usually, venules unite to form veins. The postcapillary venules normally join the capillaries exiting from a capillary bed. The walls of the venules contain anendothelium（鳞状内皮细胞），肌肉细胞和elastic fibers和一个外层结缔组织纤维。

静脉s and capillaries are the primary sites of the diapedesis. They are extremely porous which allow the blood to move easily. High endothelial venules have an endothelium made up of simple cuboidal cells.

What are the Similarities Between Vein and Venule?

两者都是人体静脉系统的一部分。
两种血管类型都有低血压。
Both transport deoxygenated blood.
Both contain thinner walls.

摘要 - 静脉VS VENULE

静脉和静脉是人体静脉系统的一部分，有助于将血液运回心脏。静脉是将血液传递到心脏的血管。除了肺静脉和脐静脉外，它们具有脱氧血液。静脉包含瓣膜，使血液流向心脏，并且仅在被挤压时打开。另一方面，静脉从毛细血管流到较大的静脉。静脉是较小的容器。许多静脉结合在一起，形成大小的静脉。与动脉相比，静脉和静脉的壁均较薄。这是静脉和静脉之间的区别。
