Niels Bohr was born and educated in Copenhagen, Denmark. He lived, worked, and died there, too. But his mark on science and history was worldwide. His professional work and personal convictions were part of the larger stories of the century.
Salivary pH Test: While generally more acidic than blood, salivary pH mirrors the blood (if not around meals) and is also a fairly good indicator of health. It tells us what the body retains. Salivary pH is a fair indicator of the health of the extracellular fluids and their alkaline mineral reserves.
The extracellular fluid also includes the transcellular fluid, which comprises about 2.5 percent of the ECF. In humans, the normal glucose concentration of extracellular fluid that is regulated by homeostasis is approximately 5 mM/L, and the pH is tightly regulated by buffers around 7.4. Interstitial fluid â the extracellular fluid bathing most tissues, excluding the fluid within the lymph and blood vessels. 2  Blood plasma â the yellow or gray-yellow, protein-containing fluid portion of blood in which the blood cells and platelets are normally suspended.
