Question

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

Answer 1

Arteries for all intents and functions carry oxygen-rich blood far away from the coronary heart and where it certainly wishes to head, which essentially is quite full-size. Veins form of bringing deoxygenated blood to the coronary heart wherein it particularly is directed to the lungs to get hold of oxygen, actually opposite to popular belief. Blood form of is the shipping media of without a doubt nearly the whole lot within the frame in a completely important way.

Complete answer:
As blood certainly is pumped without delay into arteries by way of the coronary heart, the strain usually is reasonably excessive which helps in distributing oxygen without a doubt rich blood to all body components in a diffuse manner. Subsequently, arteries should honestly have specifically thick elastic walls sustain the strain and surely do not require valves in a foremost way. Valves specifically are the form of the present in veins to especially save you backflow of the blood, or so that they virtually concept. Artery vessels which without a doubt pump blood at surely high stress far from the heart, demonstrating how arteries vessels which mainly pump blood at very excessive strain far away from the coronary heart, or so that they are honestly ideal. They kind of do no longer for the maximum component have valves as their partitions are tremendously muscular, displaying how valves are very present in veins to save you backflow of the blood, or so that they for all intents and purposes idea.

Hence, the correct answer is option (D).

Note: The arteries kind of are the blood vessels that supply oxygen-rich blood from the heart to the tissues of the frame in a predominant manner. Every artery is a muscular tube lined via fairly smooth tissue and has three layers: The intima, the inner layer covered via a quite easy tissue called the endothelium, demonstrating that the arteries generally are the blood vessels that essentially supply oxygen-wealthy blood from the heart to the tissues of the body, which kind of is fairly massive.
