...of reabsorption occurring in the nephrons. This allows for the variable intake of water and sodium seen day to day to not drastically alter blood pressure or intravascular volume, i.e....
The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the nephron. They have an important role in the absorption of many ions and in...
...means almost 99% of the water filtered is either reabsorbed into the circulation or enters the interstitium. Water Filtration and Reabsorption in the Nephron In the glomerulus, water is initially...
...of the Loop of Henle. This means a very small proportion of K+ reaches the distal nephron. Proximal Convoluted Tubule K+ reabsorption occurs passively within the PCT and about two-thirds...
...concentration gradient, out of the nephron and back into the bloodstream, thus normalising plasma osmolality and increasing total blood volume. In response to decreased plasma osmolarity, ADH release is reduced....
...principal cells of the collecting ducts in the nephron. It increases the expression of apical epithelial Na+ channels (ENaC) to reabsorb urinary sodium. Furthermore, the activity of the basolateral Na+/K+/ATPase...
The nephron is the basic functional unit of a kidney. It consists of three parts: the renal corpuscle, the filtering component, the renal tubule, which is responsible for absorption and...
Ion transport along the nephron is essential for the reabsorption of sodium and water, maintenance of plasma volume, blood pressure and production of urine. The Loop of Henle contributes to...
...by dilating the afferent arteriole of the glomerulus, increasing glomerular filtration rate (GFR). Moreover, ANP inhibits sodium reabsorption along the nephron. Conversely, ANP secretion is low when blood pressure is...
