How is water transported in the kidney
The transport of water in kidney.
Human excretory system consists of a pair of kidneys, a pair of ureters, urinary bladder and an urethra. Kidneys are the excretory organs containing the structural and functional units called the nephrons.
A nephron consists of a renal corpuscle made up of the Bowman’s capsule and a renal tubule consisting of a proximal convoluted tubule (PCT), a Henle’s loop and a distal convoluted tubule (DCT) opening into the collecting tubule. The Bowman’s capsule is made up a mass of blood capillaries.
The movement of water or the formation of urine in the kidneys involves the following processes.
- Glomerular filtration- The blood with dissolved waste materials, salt, glucose and other substances gets filtered through the Bowman’s capsule by a process called the glomerular filtration. The glomerular filtrate containing the water, excess salts, glucose and the waste products like urea is called the primary urine.
- Tubular reabsorption- The filtrate along with essential materials like water, glucose, amino acid...
