What are veins in simple terms?
Vein: A blood vessel that carries blood that is low in oxygen content from the body back to the heart. Veins are part of the afferent wing of the circulatory system, which returns blood to the heart. In contrast, an artery is a vessel that carries blood that is high in oxygen away from the heart to the body.
How do you explain arteries to kids?
Arteries are the large vessels that carry blood through the heart, around to every part of your body. The blood that arteries carry from the lungs is full of oxygen. As they get closer to the surface or into smaller spaces, blood is transferred into microscopic vessels called capilliaries.

What are veins class 10?
Veins are the blood vessels present throughout the body. They are tube-like, translucent structures that function by carrying deoxygenated blood from the tissues to the heart for re-oxygenation. Compared to arteries, veins are thin-walled.
