Textbook Question
Chapter 50, Problem 6A
You are studying renal function in different species of mammals that are found in very different environments. You look at species from a desert environment and compare them with ones from a tropical environment. The desert species would be expected to have
a. shorter loops of Henle than the tropical species.
b. longer loops of Henle than the tropical species.
c. shorter proximal convoluted tubule than the tropical species.
d. longer distal convoluted tubules than the tropical species.
