Physical Relationships in Blood-Tissue Gas Transport
In the previous chapter we discussed, in a qualitative way, certain general properties of the blood that are of importance in its gas transport function. In this chapter, we take the further steps of (1) placing this function of the blood in relation to the entire gas transport system and (2) deriving, from the laws of physics, quantitative relations among the relevant properties of this system that govern the transfer of oxygen to metabolizing tissue as well as carbon dioxide removal from it. Our goal is an evaluation of the particular importance of the prevailing values of those properties of the blood associated with the execution of this function, and of how these properties are coordinated with the functioning of the entire transport system. This chapter serves furthermore as an introduction to the more detailed analysis that appears in Chapters 5 and 6.
