stores up in its tissues. During the interval between the meals, the
liver gradually redigests the glycogen, reconverting it into sugar, and
thus supplying it to the blood in small quantities, instead of allowing
the entire amount formed in digestion to enter the circulation at once.
If too large an amount of sugar entered the system at once, it would be
unable to use it all, and would be compelled to get rid of a
considerable portion through the kidneys. The liver also completes the
digestion of albumen and other food elements."
