hi

buddy ✌️✌️✌️✌️

❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

a. The blood enters the kidney through the renal artery, which branches into many capillaries associated with glomerulus.

b. The water and solute are transferred to the nephron at Bowman’s capsule.

c. In the proximal tubule, some substances such as amino acids, glucose, and salts are selectively reabsorbed and unwanted molecules are added in the urine.

d. The filtrate then moves down into the loop of Henle, where more water is absorbed.

e. From here, the filtrate moves upwards into the distal tubule and finally to the collecting duct. Collecting duct collects urine from many nephrons.

f. The urine formed in each kidney enters a long tube called ureter. From ureter, it gets transported to the urinary bladder and then into the urethra.

Explanation:

DEFINATION

A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. The nephron functions through ultrafiltration.

STRACTURE

  1. This nephron contains a loop of Henle, so it is a mammalian nephron.
  2. While the loop of the nephron is special to mammals, the rest of the structure is seen in all vertebrate animals.
  3. The glomerulus is the net of capillaries inside of the glomerular capsule (aka Bowman’s capsule).
  4. While the picture shows the glomerular capsule and the rest of the renal tubule look to be the same in the graphic below, they are in fact composed of a wide variety of cell types, intended to extract and retain certain chemicals within the tubules.
