Question

Which of the following correctly represents the order in which oxygenated blood travels from the lungs to the body?

• A. Pulmonary vein $\to$ Left atrium $\to$ Left ventricle $\to$ Aorta
• B. Aorta $\to$ Left atrium $\to$ Left ventricle $\to$ Pulmonary vein
• C. Aorta $\to$ Left ventricle $\to$ Left atrium $\to$ Pulmonary vein
• D. Pulmonary vein $\to$ Left ventricle $\to$ Left atrium $\to$ Aorta

Answer 1

The correct option is A Pulmonary vein $\to$ Left atrium $\to$ Left ventricle $\to$ Aorta

The freshly oxygenated blood from the lungs is carried via the pulmonary vein to the left atrium. The blood is then moved to the left ventricle. The aorta finally carries the oxygenated blood to all cells of the body from the left ventricle.
