Why are human cardiac systems referred to as 'Double Circulatory Systems'?
The heartrate can be doubled to pump more blood around the body when exercising.
There are two 'dubs' (dub-dub) in one heart beat.
The blood moves through the heart twice to be pressurized twice.
Becasue there are two different kinds of blood vessels that are attached to the heart (arteries and veins).
Why do arteries have very thick and elastic walls.
