Questions & Step-by-Step Solutions

Which of the following is a mechanism of renal autoregulation?
  • Step 1: Understand what renal autoregulation means. It is the kidney's ability to maintain a stable filtration rate despite changes in blood pressure.
  • Step 2: Learn about tubuloglomerular feedback. This is a specific process that helps the kidneys adjust their function.
  • Step 3: Recognize that when blood pressure changes, the kidneys can sense this change.
  • Step 4: If blood pressure increases, the kidneys will adjust to prevent too much fluid from being filtered.
  • Step 5: If blood pressure decreases, the kidneys will adjust to allow more fluid to be filtered.
  • Step 6: Conclude that tubuloglomerular feedback is indeed a mechanism of renal autoregulation.
