Which part of the nephron is primarily responsible for the reabsorption of filtrate based on homeostasis needs?
Understand the Problem
The question is asking which part of the nephron is mainly responsible for reabsorbing substances from the filtrate based on the body's homeostatic requirements. This involves understanding the functions of various parts of the nephron in relation to filtration and absorption processes.
Answer
Proximal convoluted tubule (PCT).
The proximal convoluted tubule (PCT) is the part of the nephron primarily responsible for the reabsorption of filtrate based on homeostasis needs.
Answer for screen readers
The proximal convoluted tubule (PCT) is the part of the nephron primarily responsible for the reabsorption of filtrate based on homeostasis needs.
More Information
The PCT is crucial for reabsorbing the most essential substances, such as glucose, amino acids, and significant amounts of ions and water, contributing to the kidney's role in maintaining body homeostasis.
Tips
A common mistake is confusing the proximal convoluted tubule with other parts of the nephron, such as the loop of Henle or the distal convoluted tubule, which play different roles in the reabsorption and secretion process.
