===Juxtaglomerular Apparatus===
===Juxtaglomerular Apparatus===
* The terminal portion of the straight distal tubule contacts the afferent and efferent vessels supplying its own glomerulus
* The terminal portion of the straight distal tubule contacts the afferent and efferent vessels supplying its own glomerulus
* These vessels are said to embrace the distal tubule
