The above diagram shows the exchanges that take place between the capil-
laries and tissues. At the arterial end of the capillary, blood pressure is high-
er than osmotic pressure—thus water, oxygen, amino acids and glucose tend
to leave the bloodstream. At the venous end of the capillary, however, the sit-
uation is exactly reversed: Osmotic pressure is higher than blood pressure.
Therefore, water, carbon dioxide and other waste molecules tend to enter
the bloodstream. This perfect process, arising from pressure differences,
enable oxygen and nutrients to be distributed throughout the body and waste
products to be removed.

uisite tissues, or else too much. This would mean that the tis-
sues would either burn out from too much oxygen or die from
too little.
All this information about the hemoglobin molecule con-
firms that its structure was especially created for life. Thus,
this molecule represents a major dilemma for Darwinists, who
ascribe the development of life on Earth entirely to coinci-
dences. If Darwinists are to insist that hemoglobin is the
product of chance-based mutations, then they must
explain how the genetic information of the hemo-
