Question

Which parts of the heart pumps deoxygenated blood to the lungs?

• A. 1, 2 and 6
• B. 1, 2 and 7
• C. 2, 4 and 6
• D. 3, 4 and 5
• E. 3, 4 and 8

Answer 1

The correct option is A 1, 2 and 6

Both venae cavae (7) pass the deoxygenated blood to the right atrium. Blood from the right atrium (1) enters right ventricle (2) and pulmonary arteries (6) carry deoxygenated blood from right ventricle to lungs for oxygenation. Two pulmonary veins (8) come from each lung and pass oxygenated blood to left atrium (3). The left ventricle (4) pumps blood into the aorta (5) which in turn branches and delivers blood to the major body regions and organs. So, the correct answer is option A.
