Veins are darker than arteries because they have thin walls, and the darker blood shows through them more easily. Arteries are lighter in color because they have thicker walls containing connective tissue which is lighter in color in preserved material. The veins probably look wider because they collapse when the heart stops beating. When they collapse, they flatten out, making them wider.

Why do you say that the larger lymph vessels are comparable to veins rather than arteries?
Veins have wider lumens than arteries. Veins have thin muscular walls since low pressured blood passes through veins. the walls of the veins however have the same components as in arteries, that is, they have a muscular wall, a connective tissue wall, an endothelium and a layer of elastic tissue. Since arteries experience higher pressured blood the muscular player is much thicker than the one in the veins. therefore, the lumen of the artery is much smaller than that of the vein. Therefore, since lymphatic materials must pass through lymph vessels having the materials being somewhat large, a wider lumen is needed, like that of the veins.

Are veins thicker than arteries?
The tunica media is thicker in arteries than in veins.
What does an artery have that a vein does not?
Arteries carry oxygenated blood; veins carry de-oxygenated blood. Arteries have much thicker muscular wall (of muscle and elastic fibres). Arteries have narrow passageway for blood; veins have a wider passageway. Arteries have higher blood pressures. Extra info. if you need it Veins have flaps of valves while arteries do not.
What is the blood vessel connecting capillaries to arteries?
Venules, they are smaller and thinner than veins.
Which is larger retinal arteries or retinal veins?
Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
Where is the pushing force of the heart greater in arteries or in the veins?
The pushing force of the heart is greater in arteries than in veins. The arteries are closer to the heart itself.
What is the amount of muscle in veins and arteries?
The amount of muscle in veins and arteries varies in the sense that arteries are more muscular than veins to give them extra elasticity and strength to deal with surges of blood.
Blood pressure is higher in veins than arteries?
No, pressure is higher in the arteries.
What are facts about veins and arteries?
If you gather all the veins and arteries together in your body, then it could wrap around the earth, twice!There are some veins and arteries that are smaller than a price of your hair!
Name three blood vessels?
the three blood vessels are the Veins capillaries Arteries the arteries.
What do arteries and veins drain?
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.)
