which of the following helps maintain a high solute concentration in the kidney medulla?\nmultiple choice\nhigh urea concentration in medulla\nactive transport of solutes from the ascending loop of henle\nsolutes transported across the basolateral membranes of the loop of henle\nall of the choices are correct.
Answer
Brief Explanations:
- High urea concentration in the medulla contributes to the osmolarity gradient.
- Active transport of solutes from the ascending loop of Henle helps build the gradient.
- Solutes transported across the basolateral membranes of the loop of Henle also play a role.
Answer:
All of the choices are correct.
