Answer 2

Answer:

1)

.the largest artery is the aorta.....

2).

If arteries have thin walls they would burst because of high blood pressure. That is why arteries have thick walls. Because the heart pumps blood at high pressure. They must be able to withstand the tremendous pressure from a beating heart. Veins have thinner walls because they need more room to hold blood.

3).

One of the major differences between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart with the exception of pulmonary arteries and veins.

4).

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
