Question:
Explain the process of urine concentration and the role of antidiuretic hormone (ADH) in this process.
Answer:
Urine concentration involves removing excess water from the filtrate as it passes through the collecting ducts in the kidneys. Antidiuretic hormone (ADH) regulates this process by increasing the permeability of the collecting ducts to water, allowing for water reabsorption and urine concentration.
