blood travels away from the heart through arteries and blood travels to the heart through the veins
Capillaries connect the smallest branches of arteries and veins The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
You must learn that the term artery and vein are anatomical terms. Arteries Always carry blood Away from the heart. And veins bring blood back to the heart. Arteries are not always oxygen filled and veins are not always carbon dioxide filled. Since the pulmonary veins are carrying blood back from the lungs to the heart, they must have more oxygen.

the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Cellulose is what surronds veins and arteries.

Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
The tunica media is thicker in arteries than in veins.
