Cardiovascular Physiology

End-of-Chapter Case Study Answers

Case 1.1 1. b is correct. The circulation time will be shortened because some blood passes through the shunt (short circuit). Case 2.1 1. c is correct. When the extracellular K + concentration increases, the Nernst equation indicates that the…
