CHAPTER 39. Transport of Acids and Bases

Gerhard Giebisch, Erich E. Windhager, Peter S. Aronson

The lungs and the kidneys are largely responsible for regulating the acid-base balance of the blood (see Chapter 28). They do so by independently controlling the two major components of the body's major buffering system: CO2 and image (Fig. 39-1). Chapter 31 focuses on how the lungs control plasma [CO2]. In this chapter we see how the kidneys control plasma [image].
