The correct answer is: The circulatory system moves blood through the heart in a specific sequence, ensuring that oxygen-rich and oxygen-poor blood do not mix. The heart is divided into four chambers: the right atrium, right ventricle, left atrium, and left ventricle.<\/p>\n\n\n\n This cycle repeats continuously to supply oxygen and nutrients to the body while removing carbon dioxide and waste.<\/p>\n\n\n\n Here is an anatomical diagram of the human heart illustrating the correct pathway of blood circulation. The diagram labels the major structures and uses arrows to indicate the flow of oxygenated (red) and deoxygenated (blue) blood.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following is the correct order of blood movement through the heart?

b.) vena cava \u2192 right atrium \u2192 right ventricle \u2192 pulmonary artery \u2192 lungs \u2192 left atrium \u2192 left ventricle \u2192 aorta \u2192 body<\/strong><\/p>\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n
Blood from the body, which is low in oxygen and high in carbon dioxide, returns to the heart through two large veins: the superior vena cava<\/strong> (from the upper body) and the inferior vena cava<\/strong> (from the lower body). This blood enters the right atrium<\/strong>.<\/li>\n\n\n\n
The right atrium contracts, pushing blood through the tricuspid valve<\/strong> into the right ventricle<\/strong>.<\/li>\n\n\n\n
The right ventricle pumps blood through the pulmonary valve<\/strong> into the pulmonary artery<\/strong>, which carries the blood to the lungs for oxygenation.<\/li>\n\n\n\n
In the lungs, carbon dioxide is released, and oxygen is absorbed. Oxygenated blood then returns to the heart through the pulmonary veins<\/strong> into the left atrium<\/strong>.<\/li>\n\n\n\n
The left atrium contracts, pushing blood through the mitral (bicuspid) valve<\/strong> into the left ventricle<\/strong>.<\/li>\n\n\n\n
The left ventricle pumps oxygen-rich blood through the aortic valve<\/strong> into the aorta<\/strong>, which distributes blood to the entire body.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/03\/image-334.png\")
