Yes, arterial blood contains waste material.
Let's follow the blood circulation.
The arteries carry blood to all tissues in the body, and the veins carry the waste products from these tissues back to the heart.
From there it is pumped into the lungs, where a major waste product (
Other wastes are still there.
Blood carrying these wastes returns to the heart, where it enters the arterial blood supply and travels to other tissues, including the liver, kidneys, and spleen — the major waste removing organs.
Simply put, if there were no waste products in arterial blood, we wouldn’t need a liver, kidneys, or spleen.
