关键区别 - 正弦vs Capillaries
血液循环在生物的生存中起重要作用。它由不同的组成部分,例如heart作为抽水设备,血液作为带有的循环介质静脉,动脉、毛细血管等。循环系统功能s in the transportation of different components which are essential for our survival. It mainly transports oxygen and nutrients so that the cells could absorb and transport metabolic waste from the cells to the excretory organs. Capillaries are small blood vessels which involve in the exchange of different materials. Sinusoids have a similar function to that of capillaries. They only differ in structure.毛细血管possess a continuous and complete basal membrane whilst the sinusoids possess only discontinuous incomplete basal membrane.这是关键区别在毛细血管和正弦体之间。

什么是正弦?
正弦曲线是一种类型的血管,类似于染色endothelium。The basal membrane is discontinuous, unlike the capillaries. Sinusoids are also known as open pore capillaries. The permeability increases with the presence of open pores. Also, the number of tight junctions and inter-cellular clefts increase the permeability. This permeability allows small蛋白质进入并从血液中退出。正弦有一个流明which is about 30 microns and has thin walls. The lining of sinusoids contains内皮细胞with吞噬细胞。
正弦体大多存在肝,,,,脾and骨髓。肝正弦波是类似于常见的正弦的另一种正弦血管。它还具有停用的上皮或基底膜。肝正弦体为生活系统提供了特殊的功能。它充当了血液混合的部位,该部位是富含氧气的富含氧气动脉和血液的富含氧气的部位,该动脉和血液从门静脉中富含营养。这为从中获取的营养提供了机会小肠肝脏再次被体细胞吸收。
什么是毛细血管?
血毛细管是一个挖空的管状结构,有一个厚的细胞壁(内皮)。直径约为5至10微米。毛细血管可以定义为通过动脉和静脉输送血液的最小类型的血管。许多物质与间质流体围绕着这些毛细管容器。近端部分中的水,氧气和葡萄糖是在远端的水中退出毛细血管的物质,carbon dioxide,,,,尿酸,,,,乳酸,尿素和肌酐enter the capillaries.
从心脏通过动脉飞来的血液小动脉which are the narrow branches of arteries. These arterioles are further branched into capillaries. The wastes and the nutrients are exchanged here. The venules are formed when the capillaries are widened and joined together. When the组织is metabolically active, more capillaries are needed to provide nutrients and carry away wastes. There are three types of capillaries namely, continuous, fenestrated and discontinuous (sinusoidal).
When the capillaries are continuous where an endothelial cells form a lining which is not interrupted, it is known as连续的毛细血管。这些使小颗粒(例如某些离子和水)通过细胞间裂缝移动。但,lipid可溶的颗粒,扩散通过内皮细胞。
毛细血管consist of small pores on endothelial cells which allow some proteins and small molecules to diffuse through. Mostly these type of blood capillaries is found in renal肾小球。
不连续的毛细血管are located on the endothelium and have large open pores. These allow red and white cells and血清蛋白质可以通过。不连续的毛细血管在骨髓和淋巴结。
What is the Similarity Between Sinusoids and Capillaries?

摘要 - 正弦vs Capillaries
正弦and capillaries are structures in which exchange of different materials take place. This includes the exchange of oxygen and nutrients from the blood to the cells and waste materials from the cells to blood. Sinusoids possess incomplete basal membrane which appears as discontinuous. Capillaries possess complete and continuous basal membrane. Sinusoids are typically present in liver and spleen and also in the bone marrow. Capillaries are present in most of the important tissues of the body which includes, heart, muscles, lung and中枢神经系统。这是正弦和毛细血管之间的差异。
