Aya/Erik -- please stop playing games. Your second answer shows that you haven't even read the question and the possible answers.

Erik your wrong again. If arteries go away from the heart then why would this go away to? The answer is Towards the heart. Look it up better. A website called SEER.Look it up!
Its B
oh my gosh , I read it in this website SEER too and its say , stay away . my was corrected . AAAAAAAAAAAAAAA
Veins carry blood toward the heart.
Its B. Towards
The correct answer is A. Away from.
To understand why veins carry blood away from the heart, it's important to have a basic understanding of the circulatory system. The circulatory system is responsible for transporting blood throughout the body. The heart is a vital organ that pumps blood to all parts of the body.
There are two main types of blood vessels in the circulatory system: arteries and veins. Arteries carry oxygenated blood away from the heart to the rest of the body, while veins carry deoxygenated blood back to the heart.
When the heart pumps, it creates pressure that pushes blood through the arteries, which have thick and elastic walls to handle the force. As blood flows through the body and reaches its destination, it loses oxygen and nutrients and picks up waste products.
At this point, the blood needs to return to the heart to be reoxygenated and re-energized. This is where veins come in. Veins have thinner walls than arteries and contain valves that prevent blood from flowing backward.
Veins use a combination of mechanisms to bring blood back to the heart. One of the most crucial mechanisms is the contraction of skeletal muscles surrounding the veins. When these muscles contract, they squeeze the veins and push the blood towards the heart.
In summary, veins carry blood away from different parts of the body and towards the heart to be reoxygenated and re-energized.
