Verified step by step guidance
1
Understand the function of the left atrium: The left atrium receives oxygen-rich blood from the lungs to be pumped into the left ventricle and then distributed throughout the body.
Identify the vessels involved in transporting blood to the heart: The main vessels that return blood to the heart are veins, which carry blood back to the atria.
Differentiate between oxygen-rich and oxygen-poor blood: Oxygen-rich blood is typically found in the pulmonary veins, while oxygen-poor blood is found in the vena cavae.
Recognize the role of pulmonary veins: Pulmonary veins are responsible for carrying oxygen-rich blood from the lungs to the left atrium of the heart.
Eliminate incorrect options: Inferior vena cava and superior vena cava carry oxygen-poor blood to the right atrium, and pulmonary arteries carry oxygen-poor blood from the heart to the lungs.
