Starting from the left atrium, put the following in the correct order for the circulation of blood: left atrium, vena cava, aorta, lungs, pulmonary artery, right atrium, pulmonary vein, right ventricle, left ventricle. The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve, which opens to allow the blood flow through and closes to prevent blood backing up the atrium. Does it surprise you that echinoderms are more closely related to our own phylum (Chordata) than other phyla?
