It is where your blood flows throughout your body. It is connected to your heart.
To keep the blood flow moving throughout the body, and provide us with nutrients and dispose of any toxins or wastes.
The circulatory system helps the body function by having oxygen rich blood flow through the body. Also delivering oxygen rich blood to the heart so your heart can keep pumping because it has oxygen rich blood in it.
