What returns blood to the heart?

Understand the Problem

The question is asking about the physiological mechanisms or structures that are responsible for returning blood to the heart after it has circulated through the body. Specifically, it is likely inquiring about the veins or specific venous structures involved in this process.

More Information

Veins carry deoxygenated blood back to the heart, while arteries transport oxygenated blood away from the heart.

Tips

A common mistake is confusing veins and arteries; remember veins return blood to the heart, and arteries take blood away.
