The Role of the Nephron
The nephron is the functional unit of the kidney, responsible for filtering blood and producing urine. It consists of a renal corpuscle and a renal tubule, where reabsorption and secretion occur.
Reabsorption Process
- During filtration, various substances are filtered from the blood into the nephron.
- The renal tubule reabsorbs essential nutrients and substances back into the bloodstream.
- Substances like glucose, amino acids, and a significant amount of water are reabsorbed efficiently.
Urea's Fate
- Urea is a waste product formed from protein metabolism.
- Unlike glucose and amino acids, urea is not essential for the body's functioning.
- The majority of urea remains in the filtrate and is excreted in urine.
Why Urea is Not Reabsorbed
- Urea is a small, waste molecule that does not require reabsorption for the body's needs.
- The nephron selectively allows reabsorption of valuable substances while eliminating waste.
- Maintaining a balance of waste products, including urea, is crucial for homeostasis.
Conclusion
- In summary, while glucose, amino acids, and water are reabsorbed into the blood, urea is primarily excreted as waste.
- This selective process is vital for maintaining the body's internal environment, making urea the correct answer to the question.
