Consider the following statements regarding human blood circulation: 1. Deoxygenated blood from the upper body is returned to the right atrium through the superior vena cava. 2. The pulmonary artery carries oxygenated blood away from the lungs back to the left atrium of the heart. Which of the statements given above is/are correct?
A. 1 only✓ Correct Answer
B. 2 only
C. Both 1 and 2
D. Neither 1 nor 2
💡 Solution & Explanation
The superior vena cava drains deoxygenated blood from superior body regions into the right atrium, making the first statement correct. The second statement is incorrect because the pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, whereas pulmonary veins carry oxygenated blood from the lungs back to the left atrium. Understanding circulatory pathways is essential for cardiovascular physiology.
