Artwork of a section through an artery and vein

Vein and artery. Artwork of a section through a vein (blue, at left) and an artery (red, at right). Veins carry deoxygenated (blue) blood to the heart, arteries take oxygenated (red) blood from the heart. Low pressure blood is helped up the thin-walled vein by the contraction of the surrounding muscles (pink). Valves in the vein lining ensure that blood can only flow one way. The artery carries high pressure blood and has thick, muscular walls. The layers of the artery wall are unfurled at top. A tough outer coat surrounds the muscle (striped), an elastic layer (holey) and a single celled inner layer

Blood Vessel Vessels Artery Vein

EDITORS COMMENTS
This artwork showcases a detailed section through an artery and vein, offering a fascinating glimpse into the intricate network of our circulatory system. The contrasting colors beautifully illustrate the distinct roles these vessels play in transporting blood throughout our bodies. On the left side, we see a serene blue vein responsible for carrying deoxygenated blood back to the heart. Its thin walls are supported by surrounding muscles depicted in delicate shades of pink, which contract to assist low-pressure blood flow against gravity. To ensure efficient circulation, valves within the vein lining cleverly allow one-way movement only. In stark contrast, on the right side stands a vibrant red artery designed to carry oxygenated blood away from the heart under high pressure. This muscular vessel boasts thick walls that enable it to withstand and regulate this forceful flow. Atop this structure, we witness unfurled layers of its wall: a tough outer coat enveloping striped muscle fibers, followed by an elastic layer with distinctive perforations and finally culminating in a single-celled inner layer. This awe-inspiring artwork not only highlights the beauty found within our anatomy but also emphasizes how essential these intricate vessels are for sustaining life itself. It serves as both an educational tool and an artistic masterpiece that celebrates human physiology's remarkable complexity.
