Answer:
DOUBLE CIRCULATION - DEFINITION
The majority of mammals (including humans) utilize a double
circulatory system.
This means that we have two loops in our body in
which blood circulates.
One is oxygenated, meaning oxygen rich, and the
other is deoxygenated, which means it has little to no oxygen, but a lot
of carbon dioxide.
