肾脏—泌尿系统的“心脏”两个起作用的肾脏,这是给每个人的正常分配。有时一个肾脏功能衰竭或捐献给另一人,即使如此,生命照常进行,因为剩下的一只肾脏容易地取代它丢失了的伙伴的工作。首先,它的工作是滤过身体的血液,提取代谢废物,以尿的形式排泄出去。另外,肾脏调节身体内细胞外液中的钠,氯化物,磷酸盐,氢及其他离子的浓度,最近研究发现,肾脏也产生影响组织活性物质如肾素,红细胞生成素(erythrogenin)及前列腺素E_2(prostaglanclin E_2)等。肾,这一对豆形的器官,位于腰部脊椎两旁,左肾略高于右肾,每个肾脏约10cm 长,5cm 宽,2.5cm 厚。
Kidney - the “heart” of the urinary system The two functioning kidneys, which is the normal distribution for everyone. Sometimes a kidney fails or donates to another, but even then life goes on as the rest of the kidney can easily replace the work of its lost partner. First, its job is to filter the body’s blood, extract the metabolic waste, and excrete it in the form of urine. In addition, the kidneys regulate the concentrations of sodium, chloride, phosphate, hydrogen, and other ions in the extracellular fluid of the body. Recent studies have found that the kidneys also produce substances that affect the tissue actives such as renin, erythrogenin and prostaglandins E_2 (prostaglanclin E_2) and so on. Kidney, this pair of bean-shaped organs, located on both sides of the lumbar spine, left kidney slightly higher than the right kidney, each kidney about 10cm long, 5cm wide and 2.5cm thick.
