Arteries carry blood away from the heart, veins carry blood to the heart, and capillaries branch off of arteries and veins. Capillaries are essentially min-arteries and min-veins.

What is the structure of microcirculation?
Microcirulation consists of terminal arterioles connected to capillaries. The capillaries are connected to post-capillary venules which are connected to the veins,
What are the differences between the structure of arteries and veins?
The walls of the artery are generally thicker and their tunica media layer contains more smooth muscle and elastic fibres. When it is not opposed by blood pressure, the walls of the artery still contracts so arteries generally appear to be smaller in histological sections. As the endothelial lining of an artery cannot contract, an artery's endothelium is thrown into folders when it constricts and it gives it a pleated appearance. Veins do not have these folds.
When blood within the pulmonary capillary network is oxygenated it travels to the heart via which structure?
It comes back through the pulmonary veins. Veins always carry blood TO the heart. This is the only case where veins are high in oxygen.
Is a blood vessel a vein or an artery?
A 'blood vessel' can be an artery, vein, capillary, or an arteriole or a venule. These last two are minor arteries or veins. While technically a muscle, the heart is sometimes referred to as the 'largest blood vessel in the body'.
What is the direction of blood flow in a capillary?
Blood flows from arteries to veins or from arterioles (small arteries) to venules (small veins) in a capillary bed.
What does a capillary?
A capillary connects arteries and veins. it is the site of diffusion of materials from cells to and from the bloodstream.

What makes a vein different from an artery in terms of the structure?
The artery has more muscle, media layer. This is used for contraction. The veins have little muscle layer, but have valves to prevent back flow.
