The proximal tubule as a part of the nephron can be divided into an initial convoluted portion and a following straight (descending) portion. [12] Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries, including 80% of glucose, more than half of the filtered salt, water and all filtered ...
Within a single nephron, regenerative abilities differ between its parts. [199] In acute toxic and ischemic injuries, the tubules are able to regenerate and restore the function of the nephron. [196] In particular, the proximal part of the nephron, through which up to two-thirds of the primary urine is absorbed, [200] has the ability to ...
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
The thin segment is a part of the renal tubule found between the proximal and distal tubules. The renal tubule and the renal corpuscle together comprise the nephron. [1] The thin segment is described as a U-shaped band, consisting of the two continuous parts: descending limb of loop of Henle; ascending limb of loop of Henle
It is highly coiled so as to increase surface area for more effective reabsorption, which occurs in this part of the metanephridium. The distal tubule of the mammalian kidney is the portion of the nephron located between the macula densa region and the cortical collecting tubule. It consists of various subsegments that differ in structure and ...
This is followed by a renal tubule that passes from the cortex deep into the medullary pyramids. Part of the renal cortex, a medullary ray is a collection of renal tubules that drain into a single collecting duct. [citation needed] Renal histology is the study of the microscopic structure of the kidney.
Uriniferous tubules: any of the small tubules that are the excretory units of the vertebrate kidney; Uveoscleral pathway: a tubule that drains excess aqueous humor; Vasa efferentia: convoluted tubules that lead from the rete testis to the vas deferens and form the head of the epididymis [2]
