The left and right ventricles are stronger pumps. The left ventricle is the strongest because it has to pump blood out to the entire body. When your heart functions normally, all four chambers work together in a continuous and coordinated effort to keep oxygen-rich blood circulating throughout your body.
Q. Which of the following best describes pulmonary circulation?
The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart. The term pulmonary circulation is readily paired and contrasted with the systemic circulation.

Q. Where does pulmonary circulation begin?
Anatomy. The pulmonary circulation begins at the pulmonary valve, marking the vascular exit from the right side of the heart, and extends to the orifices of the pulmonary veins in the wall of the left atrium, which marks the entrance into the left side of the heart.
Q. Why is pulmonary circulation called lesser circulation?
Although the entire cardiac output flows through the lung, the pulmonary circulation has long been a second-class citizen. It has been called the “lesser” circulation in comparison to the “greater” or systemic circulation.
Q. What circulation involves When blood flows from the heart to the lungs and back to the heart?
The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.
Q. How will you describe the sequence of the oxygen carbon dioxide and blood flow in your own words?
Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
Q. Is the aorta Part of the systemic circulation?
The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
Q. Is the aorta pulmonary or systemic?
The Aorta. The aorta is the largest of the arteries in systemic circulation. Blood is pumped from the left ventricle through the aortic valve into the aorta.
Q. What happens to blood pressure and flow as it travels through vessels of the systemic circulation?
In the arterial system, as resistance increases, blood pressure increases and flow decreases. In the venous system, constriction increases blood pressure as it does in arteries; the increasing pressure helps to return blood to the heart.
Q. Which vein is the only vein that carries oxygen rich blood?
pulmonary vein
Q. Are the largest veins that carry oxygen-poor blood back to the heart?
The veins that return oxygen-poor blood to the heart are the superior vena cava and the inferior vena cava. The pulmonary veins return oxygen-rich blood from the lungs to the heart.
Q. Does artery always carries oxygen rich blood?
The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
Q. What are the arteries does not contain oxygen rich blood?
The pulmonary artery carries blood from the heart to the lungs, where it receives oxygen. It is unique because the blood in it is not “oxygenated”, as it has not yet passed through the lungs. The other unique artery is the umbilical artery, which carries deoxygenated blood from a fetus to its mother.
