Final answer:
Veins are the vessels that carry blood from the capillaries back to the heart, and they are equipped with valves to prevent backflow.
Step-by-step explanation:
Vessels that transport blood from the capillaries toward the heart are known as veins. Veins are an integral part of the circulatory system and are responsible for carrying deoxygenated blood back to the heart. They are equipped with valves that help maintain the direction of blood flow and prevent backflow. The vessels that carry blood away from the heart are arteries, while capillaries are small, thin-walled vessels where gas and nutrient exchange occurs. Lymphatic vessels are part of the lymphatic system and are responsible for transporting lymph, not blood, across the body.
