Pulmonary Function

  • Michael S. Sagiv


The purpose of respiration is to provide oxygen to the tissues and to remove CO2 from the tissues [1]. Humans are able to extract oxygen from the atmosphere and transport it to their cells where it is utilized for essential metabolic processes. The oxygen pathway from environment to mitochondria can be viewed as a cascade of resistances in chain, each one being overcome by a specific pressure gradient (Fig. 2.1). However, there are several elements in the oxygen transport pathway from mouth to mitochondria that have the individual potential to limit oxygen supply during exercise and therefore VO2max [2]. Changes of VO2 could be induced by altering the blood oxygen-carrying capacity, peripheral function, or both.
