Left ventricle pumps oxygenated blood out through aorta and to the rest of the body.
The right ventricle will pump deoxygenated blood to the pulmonary artery to get oxygenated in the lungs. Then the oxygenated blood will come back down the pulmonary vein into the left atria, and then left ventricle.
The blood never fills up the lungs, the gas exchange occurs within the capillaries in the lungs.

What happens when the ventricles of your contract?
The "beat" of your heart is the contraction of the right and left ventricles. The right atrium passes blood from the body into the right ventricle -- when the ventricle contracts, it forces shut the valve leading back to the atrium, and the blood is pushed into the pulmonary arteries that lead to the lungs. The blood returns from the lungs to the left atrium, and flows into the left ventricle. When the left ventricle contracts, the blood is pushed out of the ventricle into the aorta, the body's main artery, to be carried through the arterial system to the various parts of the body.

Where does the left atrium lead to?
The left atrium empties into the left ventricle. The left atrium and left ventricle are separated by the left AV valve, or mitral valve.
To what structures do the pulmonary arteries lead?
The right ventricle.
Starting at the right atrium in what order does blood flow through the four chambers?
The Deoxygenated blood flows from the body into the right atrium. Oxygenated blood from the lungs flows into the left atrium. Since frogs have only one ventricle, the oxygenated and deoxygenated blood mixes in the ventricle. From there, blood flows into the truncus arteriosus that contains a spiral valve to separate and lead the blood out into the body.
What happens to blood volume when the left ventricle failing but the right ventricle is ok?
When the left ventricle is failing while the right ventricle remains functioning, blood may accumulate in the pulmonary circulation due to the impaired ability of the left ventricle to effectively pump blood out to the systemic circulation. This can lead to increased pressures in the lungs and pulmonary congestion. However, overall blood volume may not significantly change; instead, there may be a redistribution of blood flow and a potential increase in venous return to the right heart. The body may also initiate compensatory mechanisms, such as fluid retention, which can further affect blood volume over time.
Where does the right atrium go after going to the right ventricle?
It goes into the pulmonary arteries. Then on to the lungs. Then into the pulmonary veins. Left atrium then ventricle. Then aorta and its 3 major branching arteries. Then to the abdominal aorta. All turn into veins which lead back to the heart.
What is the list of blood through the heart and lungs?
Blood first enters the heart from the vena cavea into the right atrium. The pumping action of the heart then moves the blood into the right ventricle. From the right ventricle the blood is pumped into the pulmonary arteries which lead to the lungs. The blood is oxygenated and returned to the heart from the pulmonary veins to the left atrium. The pumping of the heart then moves the blood into the left ventricle and with a very strong contraction sends the blood throughout the rest of the body through the aorta.
To what structures fo the pulmonary arteries lead?
The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs to be oxygenated.
Where will all venous emboli go?
All veins lead to the right atrium of the heart. After the right atrium, blood goes into the right ventricle then the pulmonary arteries to the lungs. All venous emboli will eventually end up in the lungs.
What vessel carries oxygen-rich blood from the lungs to the heart?
The pulmonary veins carry blood from the lungs to the left atrium of the heart.*Because blood vessels are classified by whether they lead into or away from the heart, the pulmonary veins are the only veins in adults that are carrying oxygenated blood, whereas the pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.
