What are the two main circulatory routes in the body?

You have lesser circulation or the pulmonary circulation. Blood goes to lungs in this system from the right side of heart. You have greater circulation or the systemic circulation. Blood goes to all over the rest of body through this circulation. The amount of blood that flows is same in both the systems. You have about 25/15 mm of Hg pressure in pulmonary circulation. You have about 120/80 mm of Hg pressure in systemic circulation.


What does the pulmonary circulation flow between?

"Pulmonary" is a fancy word meaning "lungs", therefore pulmonary circulation is just the route that blood takes between the heart and lungs, and vice versa.
