Renal artery carries oxygenated blood containing high levels of urea to the kidneys for filtration.

Answer 3

Both are blood vessels containing blood to the kidneys.

The renal artery comes off the aorta (the largest blood vessel in the body) carrying oxygen and nutrients to the kidneys.

After going through the kidneys, the blood has less oxygen, and also contains waste products from the kidneys. These are the renal veins, and return to the heart for more oxygen.

Arteries generally have thicker walls because it has to deal with a higher pressure (because it has to get to the whole body)

Veins are generally thinner because they are a much lower pressure system.
