Webloop of Henle, long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine. This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as … Web…of each tubule, called the proximal convoluted tubule, lie in the renal cortex. The tubule descends into a renal pyramid, makes a U-shaped turn, and returns to the cortex …
WebDescribe the histology of the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts; The renal structures that conduct the essential work of the kidney cannot be seen by the naked eye. Only a light or electron microscope can reveal these structures.

Webproximal convoluted tubules from distal convoluted tubules by these characteristics: 1) Staining- proximal tubules are more eosinophilic than the distal. 2) Nuclei- proximal tubule cells have more heterochromatic … The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. It can be further classified into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST).
