The correct statement about arteries is that they are elastic and contractile. Arteries are designed to withstand and regulate high-pressure blood flow from the heart. Their elastic properties allow them to stretch as blood is pumped into them, which helps maintain blood pressure during the cardiac cycle.

The ability to contract, or vasoconstrict, enables arteries to regulate blood flow and redirect it based on the body's needs, such as during physical activity or in response to temperature changes. This property is essential for maintaining correct blood circulation and ensuring that various organs and tissues receive adequate oxygen and nutrients.

In contrast, other provided statements describe characteristics that are not applicable to arteries. The rigidity and non-elastic nature imply an inability to adapt to changes in pressure, which is not true for arteries. Arteries transport oxygen-rich blood from the heart to the body, contrary to the implication of carrying oxygen-poor blood. Additionally, valves are features of veins, not arteries, preventing the backflow of blood as it returns to the heart.
