这关键区别在透析和超滤之间透析是一种人为的血液过滤过程,可以帮助患有肾脏衰竭的患者,而超滤是我们肾脏中发生的自然血液过滤的三个步骤之一。
为了减少通过代谢过程在我们体内积累的有害副产品的威胁,我们的排泄系统有效地发挥了功能,并立即将其从我们的体内移除。通过呼气,有些产品通过出汗流出时出去。除这些方法外,肾脏在排泄功能中起着重要作用。因此,肾脏负责维护身体稳态。
Not only the waste material but also kidneys remove all the other excess substances such as water, glucose, vitamins, etc. Kidneys filter blood and form urine. Urine formation primarily occurs in the nephrons, which are the functional units of the kidneys. Thus, each kidney consists of millions ofnephrons。在肾单位中,尿液形成是通过超滤,重吸收和分泌发生的。但是,由于各种疾病状况,肾脏可能无法正常运行并过滤血液。在这些医疗条件下,称为透析的过程有助于患者净化血液。

什么是透析?
Dialysis is a process that helps patients suffering from kidney failures. When the kidneys fail to functions naturally and filter blood in order to form urine and excrete waste, various harmful substances such as toxins, drugs, poisons, etc., accumulate within our bodies. It can eventually lead to fatal conditions. In these situations, dialysis is one of the medical processes that can perform to purify blood and aid in the excretory process. Hence, in simple words, dialysis is an artificial way of replacing the kidney functions. Through dialysis, small solute molecules separate from the larger solutes due to the difference in their diffusion rates. It occurs via a semi-permeable membrane.
透析有两种主要类型,即血液透析和腹膜透析。在hemodialysis, an artificial kidney or a dialysis machine is used to purify the blood. On the other hand, peritoneal dialysis does not use a machine. Instead, it uses a dialysate and the membrane lining of our abdomen in order to clean our blood.
什么是超滤?
Ultrafiltration is one of the three processes occurring in our kidneys during the blood filtration. Thus, it is the first step that takes place at the Bowman’s capsule. Blood filters fromglomerulus to the Bowman’s capsule通过超滤肾单位。肾小球是毛细管网络,它将带有废物的血液带入鲍曼的胶囊中。然后在高压下过滤血液。因此,血液中的大多数物质(球状蛋白除外,红细胞,白细胞和血小板除外)都进入肾单位。传入小动脉在肾小球上取出血液时会流血。
超滤所需的压力由于肾小球的传入(传入)和传出(传出)毛细血管之间的直径差而发展。传出动脉的直径小于传入小动脉,增加了血压并导致其过滤。同样,过滤也发生在毛细血管的膜和鲍曼胶囊的内膜之间。这种现象是通过半渗透膜在高静水压力下进行过滤是超滤过程。
Not only in kidneys but this can also be simulated in external environments to separate substances from a mixture especially in industries in order to purify solution mixtures and concentrate them. Furthermore, the principal of ultrafiltration is used in water purification processes as well.
透析和超滤之间有什么相似之处?
- Dialysis and ultrafiltration are two processes that relate to our kidney function.
- 在这两个过程中,我们的血液过滤器中的废料通过半渗透膜消失。
- 这两个过程都阻止了较大的分子通过膜。
- 这se processes have industrial applications as well.
透析和超滤有什么区别?
透析和超滤是两个重要过程。透析和超滤之间的关键区别在于过程。透析是一种临床应用,可帮助患者人为地清洁血液,而超滤是在我们肾脏中尿液形成期间自然发生的过程。此外,在透析中,溶质从高浓度沿电化学梯度移动到低浓度。但是在超滤中,由于压力梯度,物质传播。因此,这是透析和超滤之间的另一个区别。此外,透析发生在我们腹部的透析剂或腹膜衬里,而在肾小球和肾脏胶囊胶囊之间进行超滤。
Furthermore, the rate of ultrafiltration depends on the porosity of the membrane and the speed of blood flow (or the pressure created by the blood flow) while the dialysis rate depends on the dialysate flow rate. Thus, this is also a difference between dialysis and ultrafiltration.
摘要 - 透析与超滤
透析治疗,过滤器和净化the blood using a machine. It is a medical procedure. On the other hand, ultrafiltration is a natural process that takes place in our kidneys. It occurs between glomerulus and Bowman’s capsule of the nephrons. Therefore, this is the key difference between dialysis and ultrafiltration.
