Pulmonary vein
The artery leaving the right ventricle, also called the pulmonary artery, takes blood to the lungs to exchange gas.
Blood enters the heart through the inferior or superior vena cava, then goes through the right atrium, into the right ventricle, and into the pulmonary artery, which takes the blood to the lungs for oxygen.
When the right ventricle contracts it is pushes blood to the pulmonary arteries and to the capillaries of the lungs where exchange of gases takes place
Only one. The Pulmonary artery leaves the right ventricle and takes the de-oxygenated blood to the lungs.
receives blood returning to the heart from the superior and inferior vena cava.
Deoxygenated blood travels through the veins called the inferior vena cava and superior vena cave into the right atrium. Blood flows from the right atrium, through a valve and into the right ventricle and into the pulmonary arteries. From the pulmonary arteries the blood is carried to the lungs. So the answer is pulmonary artery.
The Left Ventricle has the thickest walls! The left ventricular myocardium is much thicker then the right ventricular myocardium because the left ventricle pumps blood into the aorta which takes blood to the rest of the body. (larger pressure gradient)
I don't think you have grasped the concept... Blood is pumped thru the left ventricle to the tissues, from the tissues to the veins and into the right atrium. The right atrium pumps the blood to the right ventricle, your right ventricle pushes the blood into the pulmonary arteries, this leads to the pulmonary capillaries (in which oxygenation takes place), from there to the pulmonary veins to the left atrium, then the left ventricle....
The left side of the heart is bigger because it has to pump harder to get the oxygenated blood all the way around your body. The right side merely receives de-oxygenated (venous) blood.
One of your pulmonary veins does not take blood to your right ventricle.your pulmonary arteries on the other hand take blood from the right ventricle. They take the blood to the lungs to be oxygenated. There are four pulmonary arteries, two go to your left lung and two go to your right lung.All of your pulmonary veins takes blood to your left Atrium which then moves it into your left ventricle.
The Pulmonary arteries carry deoxygenated blood from the lungs to the heart.
The Pulmonary Artery which takes the deoxygenated blood to the lungs.
