blood is pumped from the left ventricle to the lungs.
blood is pumped from which part of the heart to the lungs?
left ventricle
the left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. there are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. in mammals and birds, blood from the body goes to the right side of the heart first. blood enters the upper right atrium, is pumped down to the right ventricle and from there to the lungs via the pulmonary artery. blood going to the lungs is called the pulmonary circulation. when the blood returns to the heart from the lungs via the pulmonary vein, it goes to the left side of the heart, entering the upper left atrium. blood is then pumped to the lower left ventricle and from there out of the heart to the body via the aorta. this is called the systemic circulation. a cardiac shunt is when blood follows a pattern that deviates from the systemic circulation, i.e., from the body to the right atrium, down to the right ventricle, to the lungs, from the lungs to the left atrium, down to the left ventricle and then out of the heart back to the systemic circulation.

arteries form part of the circulatory system. they carry blood that is oxygenated after it has been pumped from the heart. coronary arteries also aid the heart in pumping blood by sending oxygenated blood to the heart, allowing the muscles to function. arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well). there are two types of unique arteries. 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.
