Blood vessels are lined with simple squamous epithelium--in fact, the entire cardiovascular system is.
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.)
Exactly i also cannot say but its because arteries- the blood vessels are thicker as compared to veins. Moreover the veins are more of superficially located as compared to arteries. We can also see the arteries though, look at the wrist joint of your hand (In most people you can see) you will see 2 thick lines running towards your elbow, but it will quickly disappear. These are nothing but the arteries.
blood travels away from the heart through arteries and blood travels to the heart through the veins
This is because arteries have more force going through them than veins do. Arteries have a higher level of pressure as opposed to veins who are more relaxed and just have blood being pushed along through them rather than FORCED. If you put a vein in place of an artery, it would probably just burst.
arteries.
Yes, but it will be a little darker inside the veins.
Inside of your veins and arteries.
The skull is in the way
Inside the veins and arteries
Veins and arteries don't enter bone. They are outside of bones. The only thing inside bone is bone marrow.
the three blood vessels are the Veins capillaries Arteries the arteries.
Most veins are thinner walled tubes than arteries, and basically transport blood towards the heart.

In the veins and venules at any given time.
These are usually simple squamous epithelial cells. The epithelium lining the body cavities is called the mesothelium and is where the cancer mesothelioma arises from. The epithelium lining arteries and veins is called endothelium.
Veins
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
