Solution
The separation of the right side and the left side of
the heart is useful to keep oxygenated and de-
oxygenated blood from mixing. Such separation
allows a highly efficient supply of oxygen to the
body. This is useful in animals that have high
energy needs, such as birds and mammals, which
constantly use energy to maintain their body
temperature.
