Blood takes a very precise route during pulmonary circulation. Two large veins called the vena cavae bring blood to the right atrium of the heart. The atrium fills with the waste-rich blood and then contracts, pushing the blood through a one-way valve down into the right ventricle.
The pulmonary circulation is the circulation of blood between the heart and lungs. The pulmonary artery is deoxygenated and travels to the lungs to receive oxygen, where it reâ¦turns back via pulmonary oxygen, now oxygenated. The systemic circulation is the circulation of blood form heart throughout the body.
