A vein is a blood vessel that conducts blood toward the heart. Compared to arteries, veins are thin-walled vessels with large and irregular lumens.
<h3>Where are blood vessels found in your body?</h3>
- Blood is delivered to human tissues by arteries, which act as conduits or channels. Two tube-like closed systems comprised of the vessels start and stop at the heart. Blood is transported from the right ventricle to the lungs and back to the left atrium by one system, the pulmonary arteries.
- Your circulatory system is made up of blood vessels and heart vessels. About 60,000 miles of blood arteries make up your body.
- Blood is carried through blood arteries throughout the body. Blood is carried away from the heart through arteries. The blood is brought back to the heart by veins. Body cells and tissues are surrounded by capillaries that transport and absorb nutrition, oxygen, and other chemicals.
- Blood vessels are the channels or conduits through which blood is distributed to body tissues.
- The arteries (red) carry oxygen and nutrients away from your heart to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

Jawless fish, cartilaginous fish, and bony fish have notochord when they were still young but it was replaced by a vertebral column as they mature.
