Effect of blood flow and metabolic rate on peripheral tissue Pco2

Pco2 from the normal value of 45 mm Hg to 41 mm Hg, down to a level almost equal to the Pco2 in the arterial blood (40 mm Hg) entering the tissue capillaries.

2. Note also that a 10-fold increase in tissue metabolic rate greatly elevates the interstitial fluid Pco2 at all rates of blood flow, whereas decreasing the metabolism to one quarter normal causes the interstitial fluid Pco2 to fall to about 41 mm Hg, closely approaching that of the arterial blood, 40 mm Hg.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
