The right side is the pulmonary circuit.
(The left side is the systemic circuit.)
The circulation of venous blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart.
The right side of the heart pumps blood to the lungs
The circulatory system>
The pulmonary circuit is powered by the right side of the heart. Its main function is to pump deoxygenated blood which has returned to the heart from the body to the lungs, then back to the heart. The blood is pumped from the heart via the pulmonary artery. The blood is then oxygenated by gas exchange between the alveoli in the lungs and the pulmonary capillaries. The newly oxygenated blood is then returned to the heart by the pulmonary veins, ready to be sent round the body.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
The circulation of venous blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart.
The right side of the heart pumps blood to the lungs
After it makes its circuit throughout the body, blood must return to the heart. the veins carry the blood back toward the heart via the superior and inferior vena cava. The vena cava empty into the right atrium of the heart to begin the cycle again.
The pulmonary circuit is blood flow movements from the pulmonary trunk to the left atrium...while the systemic circuit is a continuation from the left atrium all the way to the right atrium.......... Disclaimer [research for detailed blood movements in pulmonary circuit and systemic circuit if this isn't enough].
The heart is responsible for pumping the blood to every cell in the body. It is also responsible for pumping blood to the lungs, where the blood gives up carbon dioxide and takes on oxygen. The heart is able to pump blood to both regions efficiently because there are really two separate circulatory circuits with the heart as the common link. Some authors even refer to the heart as two separate hearts, a right heart in the pulmonary circuit and left heart in the systemic circuit. In the pulmonary circuit, blood leaves the heart through the pulmonary arteries, goes to the lungs, and returns to the heart through the pulmonary veins.
The circulatory system>
The heart is supplied with blood from the superior vena cava (the large vein that flows to the right atrium). This vein carries blood from the systemic circuit (from the body) to the heart so that blood may be oxygenated and recirculated.
The structures of the heart most closely associated with the transport of deoxygenated blood are the right atrium and the right ventricle. Deoxygenated blood from the body returns to the right atrium via the superior and inferior vena cavae, then flows into the right ventricle, which pumps it to the lungs through the pulmonary arteries for oxygenation.
Blood flows from the right atrium of the heart into the right ventricle to the pulmonary artery to the lungs where the blood is oxygenated. From there it flows to the pulmonary vein to the left atrium and ventricle, then to the aorta.
The left and right pulmonary veins carry oxygenated blood back to the left atrium of the heart
The systemic circuit ends at the vena cava, the largest vein in the body, which carries deoxygenated blood from the body back to the right atrium of the heart.
