How is the heart involved in pulmonary circulation?

Right side of the heart is involved in pulmonary circulation. This circulation is called, at times, as lesser circulation, as against the greater or systemic circulation. Blood that flows through the lesser and greater circulation is same in amount. But there is gross difference between the two. You have interstitial compartment in the systemic circulation. This is maintained through high blood pressure there. You do not have the same in pulmonary circulation. What you need here is simple blood flow, with out formation of the interstitial compartment. For that you have blood systolic blood pressure of about 25 mm of mercury. The blood pressure in the capillaries is about 15 mm of the mercury. The oncotic pressure of the blood proteins is about 22 mm of mercury. So very little fluid is leaked out to keep the alveoli wet. Some times in diseased condition more fluid is leaked out in the alveoli, to give rise to pulmonary oedema.


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.

How does fetal circulation differ from the circulation pattern after birth?

In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.
