肾脏血供丰富,肾动脉(A)经一系列分支成入球小A→血管球个出球小A→毛细血管(Cap)网回流至静脉。肾单位的功能一定依赖于其邻近间质的化学与渗透特性,而间质本身也必然反映肾小管周围的血供。现多认为,每一个肾单位的血供是由来自于多个血管球的出球小A供给。但某些表浅肾单位的肾小管由该肾单位的出球小A供血。由于在其间行走着小叶
Kidney blood supply is rich, the renal artery (A) by a series of branches into the small ball A → small ball out of the ball A → Cap network back to the vein. Nephron function must rely on the chemical and osmotic properties of its adjacent stroma, and the stroma itself also necessarily reflects the blood supply around the renal tubules. Now think that the blood supply for each unit of the necks is from a small number of blood vessels from the ball A small supply. However, some of the superficial renal tubules of the renal unit by the small unit of the A small blood supply. Due to walking in the leaflets
