Tubular fluid flows from which renal tubular segment into the collecting duct?
A
Distal convoluted tubule
B
Glomerulus
C
Loop of Henle
D
Proximal convoluted tubule
Verified step by step guidance1
Begin by understanding the structure of the nephron, which is the functional unit of the kidney. The nephron consists of several segments: the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and the collecting duct.
Identify the sequence of fluid flow through the nephron. Fluid initially enters the nephron at the glomerulus, where filtration occurs.
After filtration, the fluid moves into the proximal convoluted tubule, where reabsorption of water, ions, and nutrients occurs.
Next, the fluid travels through the loop of Henle, which is responsible for concentrating the urine by reabsorbing water and salts.
Finally, the fluid enters the distal convoluted tubule, where further reabsorption and secretion occur before it flows into the collecting duct, which is the final segment where urine is collected before being transported to the bladder.
