Textbook Question
Chapter 49, Problem 2S
John’s doctor is concerned that John’s kidneys may not be functioning properly due to a circulatory condition. The doctor wants to determine if the blood volume flowing through the kidneys (called renal blood flow rate) is within normal range. Calculate what would be a “normal” renal blood flow rate based on the following information:
John weighs 90 kg. Assume a normal total blood volume is 80 mL/kg of body weight, and a normal heart pumps the total blood volume through the heart once per minute (cardiac output). Also assume that the normal renal blood flow rate is 21% of cardiac output.

Capillary filtration plays a vital role in the exchange of fluids between the circulatory system and tissues
A. Consider a scenario where the hydrostatic pressure in the capillary bed is 40 mmHg, the osmotic pressure in the capillary is 25 mmHg, and the interstitial fluid hydrostatic pressure is 5 mmHg. Calculate the net filtration pressure in this situation.
B. Determine the direction of fluid movement across the capillary wall
Hypertension is a major health issue in the United States, yet glomerular filtration rate
is not autoregulated until mean arterial blood pressure exceeds 180 mm Hg. In contrast,
a drop in mean arterial blood pressure of only a few mm Hg sets autoregulation into
motion. What does this tell you about the regulation of blood pressure?
A healthy 48-year-old man comes to the physician with his wife for a routine examination. When asked about his diet, the patient says, "I eat health foods as long as they taste good." His wife says that her husband heavily salts all the food he eats. Under normal circumstances, which of the following responses most likely allows the patient to compensate for the excess dietary sodium?
Serum concentrations:
Aldostrone angiotensin II plasma renin activity
a. increased increased increased
b. increased increased decreased
c. increased decreased increased
d. increased decreased decreased
e. decreased decreased decreased
