Chapter 49.3, Problem 1CS
Summary Introduction
To determine: The examples besides dialysis in which the countercurrent exchange mechanism is seen.
Introduction: Countercurrent exchange refers to the process by which exchange of substances flowing in the opposite direction between two bodies occurs. The exchange may be of fluids, heat, or chemicals.

Ridney function using the creatinine clearance rate. You request a 24 hour urine sample and a
blood plasma creatinine test. The lab sent you the following information:
- 1200 mg creatinine in the 24-hour urine sample
2.1L urine collected in 24 hours
0.8 mg/dL creatinine in plasma
- 1.71 correction factor for patient's surface area
a) Compute the creatinine clearance rate. Show your work and include units for full credit.
b) Based on the table below, evaluate the patient's kidney function. Show your work.

Hello, can you help me I am stuck please!!
Scenario: Chet H. has been feeling weird lately and so he has some medical tests conducted. The doctors tell him that the dicarboxylate co-transporters on the basolateral side of his proximal tubule cells not working correctly. He comes to you to ask what the consequences of this condition will be: You tell Chet that the most direct problem will be: (see image)
