  so the nephrons are going to sort of radiate out from the central portion
  因此肾单位从中心向外呈放射状分布
• 
  
  through the medulla and up into the cortex,
  穿过髓质向上延伸进入皮质
• 
  
  with the glomerulus near the cortex,
  以及靠近皮质的肾小球

  and the Loop of Henle stretching down into the medulla.
  再向下延伸进入髓质的亨利氏环

• 
  
  that's produced by high pressure inside the arteriole system
  由小动脉系统内部的高压
•

  经由这些毛细血管的孔隙所挤出的液体的
• 
  
  The capsule, called Bowman's capsule,
  那个囊 被称为鲍曼氏囊
• 
  
  is there to catch this fluid
  就是用来收集这种滤液的
• 
  
  and start it on its way through this series of tubules.
  然后经以下一系列的小管将滤液送上旅程
