Systemic
What is the route of the pulmonary circulatory system?
From the heart
To the lungs

What route does the systemic circulatory system follow?
From the heart
To the rest of the body
And back
What happens during the systemic circulatory system?
Oxygen is passed to the cells
Carbon dioxide is collected from the cells
