ipCD – Urinary - Renal Filtrate Processing

Benjamin Cummings. InterActive Physiology® 8-System Suite CD-ROM, Benjamin Cummings, 2004.

Objective:

To explain in short essays or diagrams the processes of reabsorption and secretion in the various segments of the renal tubules and to explain their role in concentrating urine and maintaining fluid and electrolyte balance, at the level of 85% proficiency for each student.

In order to achieve this objective, you will need to be able to:

1. Explain the passive and active processes of reabsorption and secretion.
2. Explain reabsorption and secretion in the proximal convoluted tubule.
3. Explain the role of the loop of Henle in forming the medullary osmotic gradient.
4. Explain reabsorption and secretion in the distal convoluted tubule and collecting system.
5. Explain the role of aldosterone in the reabsorption of sodium and secretion of potassium; and explain the role of antidiuretic hormone (vasopressin) in the concentration of urine.
6. Explain the role of the medullary osmotic gradient in the concentration of urine.
