Which is the correct order of the filtrate path in the nephron?

The correct order of the filtrate path in the nephron begins at the glomerulus, where blood filtration occurs. The filtrate that results from this process first enters Bowman's capsule, a structure that encases the glomerulus and collects the filtrate. From Bowman's capsule, the filtrate moves into the proximal tubule, where a significant portion of nutrients, ions, and water are reabsorbed back into the bloodstream. Following the proximal tubule, the filtrate passes into the loop of Henle, which has descending and ascending limbs facilitating further concentration and dilution of the filtrate through the processes of reabsorption and secretion.

This sequential path is crucial to maintain body fluid homeostasis and filter waste products from blood effectively. Each component of the nephron plays a specific role in processing the filtrate before it reaches the distal tubule, and eventually the collecting duct, which leads to the renal pelvis and then to the ureter for excretion. Understanding this flow helps clarify renal physiology and the nephron's role in homeostasis.
