| 释义 | nephron noun[ C ] medical specializeduk /ˈnef.rɒn/ us /ˈnef.rɑːn/ a basic unit of the kidney: 肾元，肾单位 The kidneys contain millions of tiny filtering units called nephrons.肾脏中含有几百万个被称为肾元的过滤单位。 Other major organs adventitia adventitial atrioventricular node cardiothoracic convoluted tubule epicardial epicardium exocrine extrahepatic gall bladder Henle's loop pneumonic proximal convoluted tubule sense organ splanchnic spleen splenic tum viscera vital organs Examples of nephronnephron These may be further compounded by age changes in function of the nephron. It consists of dysplastic collecting tubules and nephrons leading to the formation of cysts. Similar problems can arise if the delivery of sodium to the distal nephron is reduced. In zebrafish, the kidney (analogous to the pronephros in mammals) consists of two laterally located nephrons joined by a single central glomerulus that maintains proper osmoregulation. Renal cysts arise from the tubular nephron and collecting ducts as a result of abnormal growth and function of the specialised epithelial cells that line these structures. Through reciprocal interactions, the bud is induced into bifurcation, in turn inducing the surrounding mesenchymal cells to undergo a mesenchymal-epithelial transition, eventually leading to the formation of the epithelial nephron. It then passes through thin ciliated tubules into the pronephric nephron where it is processed for solute recovery.

Many of the kidney's functions are accomplished by relatively simple mechanisms of filtration, reabsorption, and secretion, which take place in the nephron.

Clearance is a function of glomerular filtration, secretion from the peritubular capillaries to the nephron, and reabsorption from the nephron back to the peritubular capillaries.

This cell membrane protein participates in the control of ion homeostasis at the distal convoluted tubule portion of the nephron.

At the beginning of the nephron, the renal glomerulus is a network (tuft) of capillaries that performs the first step of filtering blood.

The complex physiological function of nephron is achieved on the basis of interactions between vessels and tubules (both are hollow channels).

Cyst formation begins in utero from any point along the nephron, although fewer than 5% of nephrons are thought to be involved.
