Question

which numbers in the image represent the parts of the heart used to pump blood to the lungs?
a. 5, 6, 7
b. 1, 4, 7
c. 2, 3, 4
d. 4, 5, 6

Explanation:

To pump blood to the lungs, the heart uses the right atrium (2), right ventricle (3), and the pulmonary artery (4). The right side of the heart (blue - deoxygenated blood) sends blood to the lungs for oxygenation. So the parts are 2, 3, 4.

Answer:

C. 2, 3, 4
