how oxygenated blood returns to the heart from the lungs?
arterial blood
the heart is separated into 4 chambers. deoxygenated blood enters into the right chambers of the heart and continues through the pulmonary arteries to be oxygenated in the lungs. oxygenated blood returns into the left side of the heart and out to the rest of the body, known as the systemic circulation. in congenital heart defects such as ventricular septal defects (vsd) and atrioventricular septal defects (avsd), there may be one or multiple holes in the walls separating adjacent chambers. this causes left-to-right shunting of blood as oxygenated blood can flow back to the right side of the heart, resulting in a mixture of oxygenated and deoxygenated blood. increased amounts of blood on the right side of the heart cause an excess of blood flow into the lungs (pulmonary circulation) and increased pulmonary resistance due to the buildup of pressure.

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.
