Step 2
Explain how ONE structural feature of the vessel enables it to carry out its function.
Answer
Arteries have thick muscular walls in order to withstand the higher pressure at which blood is pumped from the heart. This structural feature allows arteries to accommodate and regulate blood flow effectively.
Veins have valves to prevent the backflow of blood due to the lower pressure at which blood passes through the veins after the capillaries. These valves ensure that blood moves toward the heart, maintaining proper circulation.
