Arteries carry blood away from the heart to body tissues. Capillaries are present near almost every body cell, and they are known as exchange vessels because they permit the exchange of nutrients and wastes between the body's cells and the blood. Veins are the blood vessesl that convey blood from the tissues back to the heart.
1. Arteries have a thicker wall than veins.
2. Arteries have a narrower lumen than veins.
3. Veins have valves whereas arteries don't.
Importantly
An artery carries blood away from the heart, while veins transport blood to the heart.
Aorta and other arteries carry oxygenated blood AWAY from the heart to different parts of the body except for pulmonary artery, which is the only artery that carries unoxygenated blood. Veins, on the other hand, carry unoxygenated blood from different body parts TO the heart except for pulmonary vein.
Arteries carry blood from the heart. They are mainly oxygen rich (not always!)
Veins carry blood to the heart. They are mainly oxygen poor (not always!)
Arteries are thicker because they have to deal with higher blood pressures
Veins are thinner, lower pressures.
Capillaries are vessels made of epithelial tissues. They are thin to allow gas exchange.

Capillaries differ from veins and arteries in that they are smaller in diameter.
The branches from arteries are arterioles and then into capillaries.
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
Capillaries
Arterioles take blood from the arteries to the capillaries. Venules take blood from the capillaries to the veins.
Capillaries are the microscopic blood vessels that connect small arteries to small veins. Blood exchange takes place in capillaries.
the three blood vessels are the Veins capillaries Arteries the arteries.
Capillaries are the structures that connect arteries to veins.
Arteries, capillaries, & veins.
Venules, they are smaller and thinner than veins.
Arteries, veins, capillaries.
Capillaries. They are the microscopic tubes that connect the veins and the arteries.
The branches from arteries are arterioles and then into capillaries.
Capillaries, arteries, and veins are the kinds of blood vessels.
Veins, capillaries and arteries is that they are all stops for blood.
Capillaries
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
Arteries, Capillaries, and Veins are three kinds of blood vessels.
