Veins carry blood from heart to different parts of the body.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Role of Veins**: Veins are blood vessels that carry blood towards the heart. This is an important distinction to make, as they are often confused with arteries, which carry blood away from the heart.
