Verified step by step guidance
1
Understand the structure of the nephron: The nephron is the functional unit of the kidney, and it consists of several parts including the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and the collecting duct.
Identify the flow of filtrate through the nephron: Filtrate is first formed in the glomerulus, then it moves to the proximal convoluted tubule, followed by the loop of Henle, then to the distal convoluted tubule, and finally to the collecting duct.
Recognize the role of the distal convoluted tubule: The distal convoluted tubule is responsible for further reabsorption and secretion processes before the filtrate moves to the collecting duct.
Determine the connection between the distal convoluted tubule and the collecting duct: The distal convoluted tubule directly connects to the collecting duct, where the final concentration of urine occurs.
Conclude that the collecting duct receives fluid from the distal convoluted tubule, as it is the last segment of the nephron before the filtrate is collected and processed into urine.
