Let me share with you a difference between pulmonary circulation and systematic circulation.
| Aspect | Pulmonary Circulation | Systemic Circulation |
| Introduction | A circulation of transportation of deoxygenated blood from the heart to the lungs for oxygenation and returning of oxygenated blood to the heart. | A circulation of transportation of oxygenated blood from the heart to the body tissues and returning of deoxygenated blood to the heart. |
| Initiation point | Right ventricle of the heart | Left ventricle of the heart |
| End Point | Left atrium of the heart | Right atrium of the heart |
| Blood Oxygenation | Oxygenates deoxygenated blood in the lungs | Supplies oxygenated blood to body tissues |
| Blood Pressure | Lower pressure | Higher pressure |
| Blood Flow Rate | Lower | Higher |
| Distance traveled by blood | Short distance between the heart and lungs | Longer distance throughout the entire body |
| Nutrient and gas exchange | Minimal exchange | Extensive exchange |
