Answer - smaller and smaller?
am i correct?

They get larger and larger to circulate more blood.

ohh

Thank YOU Rezu! :)

No, that answer is not correct. Veins leading back to the heart actually become larger and larger, not smaller. Veins carry deoxygenated blood from the body back to the heart, and as they travel closer to the heart, they merge and form larger veins. The largest vein in the body is the superior vena cava, which brings blood from the upper body into the right atrium of the heart. So, in summary, veins leading back to the heart become larger and larger.
