what is ultrafiltration in nephron ?
nephron function through ultrafiltration.
pls give proper ans class 10
Answers
Answer:
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.
please mark me as brainliest.
In renal physiology, ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule in the kidneys. As in nonbiological examples of ultrafiltration, pressure and concentration gradients lead to a separation through a semipermeable membrane
