Verified step by step guidance

Understand the function of each type of blood vessel: Arteries carry blood away from the heart, veins carry blood toward the heart, and capillaries are involved in the exchange of substances between blood and tissues.

Identify the direction of blood flow in veins: Veins are responsible for returning deoxygenated blood back to the heart from various parts of the body.

Consider the structure of veins: Veins have thinner walls compared to arteries and often contain valves to prevent backflow, aiding in the return of blood to the heart.

Differentiate between veins and other vessels: Unlike arteries, which have thicker muscular walls to handle high pressure, veins operate under lower pressure and rely on muscle contractions and valves to assist blood flow.

Conclude that veins are the blood vessels that carry blood toward the heart, distinguishing them from arterioles, arteries, and capillaries.
