Choose the correct statement that describes arteries
They have thick elastic walls, blood flows under high pressure; collect blood from different organs and bring it back to the heart.
They have thin walls with valves inside, blood flows under low pressure and carry the blood away from the heart to various organs of the body.
They have thick elastic walls, blood flows under low pressure; carry blood from the heart to various organs of the body.
They have thick elastic walls without valves inside, blood flows under high pressure and carry blood away from the heart to various organs of the body.

The correct option is D They have thick elastic walls without valves inside, blood flows under high pressure and carry blood away from the heart to various organs of the body.
The correct option is D.
Explanation of the correct option:
- Arteries supply oxygenated blood from the left ventricle to all parts of the body at high pressure.
- The high pressure is created by the pumping of the heart.
- The artery wall is thick as it is composed of three layers so that it can sustain high pressure of the blood.
- Arteries don't require valves as the chances of reverse blood flow are negligible due to the high pressure created by the heart's pumping.
Explanation of the incorrect options
Option A:
- Arteries are thick-walled, and blood flows under high pressure, but they don't bring the blood from various parts of the body to the heart.
Option B:
- Arteries carry the blood from the heart to various parts of the body, but arteries don't have thin walls, and blood doesn't flow under low pressure.
Option C:
- Arteries have thick walls and transport the blood from the heart to various parts of the body, but arterial blood doesn't flow under low pressure.
The correct statement is that the arteries have thick elastic walls without valves inside that causes the blood to flow under high pressure resulting in the movement of blood away from the heart to various organs of the body.
