Ryan just ate a very protein-rich meal. Because of this, the amino acid levels in his blood currently exceed the transport maximum and the renal threshold for amino acids (65 mg/dL). What will happen to the excess amino acids?

The descending limb of the nephron loop is relatively impermeable to solutes and freely permeable to water.
A
False
B
True
Verified step by step guidance1
Understand the structure and function of the nephron loop, also known as the loop of Henle, which is a part of the nephron in the kidney responsible for concentrating urine.
Recognize that the nephron loop consists of two main segments: the descending limb and the ascending limb, each with distinct permeability characteristics.
Identify that the descending limb of the nephron loop is primarily permeable to water but not to solutes, allowing water to be reabsorbed into the surrounding interstitial fluid.
Acknowledge that this permeability characteristic of the descending limb contributes to the concentration gradient in the renal medulla, which is crucial for the kidney's ability to concentrate urine.
Conclude that the statement 'The descending limb of the nephron loop is relatively impermeable to solutes and freely permeable to water' is true, based on the physiological properties of the nephron loop.
