Verified step by step guidance1
Begin by understanding the structure of the nephron, which is the functional unit of the kidney responsible for filtering blood and forming urine.
Identify the starting point of the filtrate's journey: the Bowman's capsule, where blood filtration begins.
Next, the filtrate moves into the proximal convoluted tubule, where reabsorption of water, ions, and nutrients occurs.
The filtrate then travels through the loop of Henle, which is crucial for concentrating urine by reabsorbing water and salts.
After the loop of Henle, the filtrate enters the distal convoluted tubule, where further reabsorption and secretion take place.
Finally, the filtrate moves into the collecting duct, where it is processed into urine and transported to the renal pelvis for excretion.
