This is permeable to certain solids, among them mineral poisons, which it absorbs as the blood flows through ("Dializing out" is the stock laboratory idiom for this method of removing impurities). 3) How can substances necessary to the blood be prevented from escaping through the porous tube...
...volcanic disturbances which in early geological times upheaved the water and land surface of the earth and killed immense quantities of fish. Extensive zones of fish remains have been found throughout the northern hemisphere in the same rocks with rich bituminous oil deposits.
