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.
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.

The left atrium empties into the left ventricle. The left atrium and left ventricle are separated by the left AV valve, or mitral valve.
The right ventricle.
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.
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.
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.
The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs to be oxygenated.
Fluid in the lungs typically indicates a condition called pulmonary edema, where excess fluid collects in the air sacs of the lungs. This can occur due to heart failure, pneumonia, or other medical conditions, and may lead to symptoms like shortness of breath and coughing up frothy sputum. Treatment often involves addressing the underlying cause and may include medications to remove the excess fluid.
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.
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.
