The proximal tubule efficiently regulates the pH of the filtrate by secreting hydrogen ions (acid) into the tubule and reabsorbing approximately 80% of the filtered bicarbonate. [6] Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries.
Reabsorption of HCO 3-occurs in the proximal tubule, in the ascending limb of the loop of Henle, and to a lesser extent in the distal convoluted tubule of the nephron. H + secretion is carried out mainly through Na + /H + exchangers in the tubules of the nephron. [150] The collecting ducts are involved in the energy-dependent secretion of H ...
Renal corpuscle showing glomerulus and glomerular capillaries Figure 2: (a) Diagram of the juxtaglomerular apparatus: it has specialized cells working as a unit which monitor the sodiujuxtaglomerular apparatus: it has three types of specm content of the fluid in the distal convoluted tubule (not labelled - it is the tubule on the left) and adjust the glomerular filtration rate and the rate of ...
Bowman's capsule (or the Bowman capsule, capsula glomeruli, or glomerular capsule) is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine. A glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the ...
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 distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule. Cells lining the tubule have numerous mitochondria to produce enough energy for active transport to take place. Much of the ion transport taking place in the distal convoluted tubule is regulated by the endocrine system.
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).
Convoluted tubule is the compound of a metanephridium which is wrapped with capillaries. 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 ...
