Which statement accurately describes blood vessel direction?

The statement that accurately describes blood vessel direction is that capillaries carry blood towards tissues. Capillaries are the smallest blood vessels and play a vital role in the circulatory system. They form a network between arteries and veins, allowing for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. As blood flows through the capillaries, oxygen is delivered to tissues, and carbon dioxide and other waste materials from the tissues enter the bloodstream, demonstrating the essential function of capillaries in supporting cellular metabolism.

Arteries, in contrast, are responsible for carrying blood away from the heart, while veins transport blood back towards the heart. The notion that all blood vessels carry blood in the same direction is incorrect, as each type of vessel has a specific role in the circulatory system, facilitating different directions of blood flow.
