What type of blood vessel returns blood to the heart?

Veins are blood vessels that specifically return deoxygenated blood back to the heart from various parts of the body. They have thinner walls compared to arteries and often contain valves that help prevent the backflow of blood, ensuring that it moves in the correct direction towards the heart. Unlike arteries, which carry oxygen-rich blood away from the heart to the body, veins play a crucial role in the circulation system by completing the circuit of blood flow. Understanding the function of veins is essential for recognizing how the circulatory system operates and sustains bodily functions.
