Renal physiology: practice question

The best answer is B, Ultrafiltration. Glomerular ultrafiltration is driven by pressure across the filtration barrier and moves water and small solutes from plasma into Bowman space.

Tubular secretion moves solutes from blood into tubule later.

Peristalsis moves urine through ureters.

Reabsorption returns useful solutes and water to blood.

It tests Renal physiology in Physiology. The correct option holds because: Correct: ultrafiltration creates initial tubular fluid.

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
