Answer is Right!
Answer is Wrong!
The correct answer is A. Arteries.
Arteries are blood vessels that carry oxygen-rich blood away from the heart to the body’s tissues. They are thick-walled and muscular, which helps them to maintain a high blood pressure and to pump blood against the force of gravity.
Veins are blood vessels that carry oxygen-poor blood from the body’s tissues back to the heart. They are thin-walled and have valves that help to prevent blood from flowing backwards.
Both arteries and veins are important for the circulatory system, but arteries play a more critical role in carrying oxygen-rich blood to the body’s tissues.
