Veins
Veins are thin blood vessels that carry blood from various body parts to the heart. These have valves in them to prevent back flow of blood.

You can use any vein. Inner arm veins are popular because they are easily found and conveniently accessible.
hyperthermia, dude

It's Renal Artery.
Who sings going to catch a cold from the ice inside your veins from?
I think you mean ice inside your soul because that is a line well kind of a line from the song "Jar of Hearts". It's sung by Christina Perri.
What vessel is prominent in many people and often used as the site for drawing blood?
median cubital vein
Are arteries thicker and stronger than veins and have two major properties?
Yes, Arteries are stronger and thicker than veins because they get more pressure from the heart. Arteries take blood away from the heart. Veins take blood toward the heart. The two major properties of artieries are their elasticity and contactility.
What roles do arteries capillaries and veins play in the cardiovascular system?
These serve in transporting blood between heart, organs, and muscles. Arteries usually leave the heart and transports blood to the body(systematic circulation) or to the lungs(pulmonary circulation).
Does your nervous system have veins?
Yes, since the brain and spine are part of the nervous system, then the nervous sytem has arteries and veins. There are major arteries in the brain.

The splenic vein (a part of the portal vein), is connected to the renal vein.

Jugular veins
Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum, such as in the case of a stream issuing out of a nozzle, (orifice). (Evangelista Torricelli, 1643).
The maximum contraction takes place at a section slightly downstream of the orifice, where the jet is more or less horizontal.
The effect is also observed in flow from a tank into a pipe, or a sudden contraction in pipe diameter. Streamlines will converge just downstream of the diameter change, and a region of separated flow occurs from the sharp corner of the diameter change and extends past the vena contracta.
The reason for this phenomenon is that fluid streamlines cannot abruptly change direction. In the case of both the free jet and the sudden pipe diameter change, the streamlines are unable to closely follow the sharp angle in the pipe/tank wall. The converging streamlines follow a smooth path, which results in the narrowing of the jet (or primary pipe flow) observed.
Measurement of the vena contracta is useful in echocardiography, where it describes the smallest area of the blood flow jet as it exits a heart valve. This corresponds to the Effective Orifice Area calculated for heart valves using the continuity equation.
For the same reason nearly every other part of the body has them. They are living tissue and so need blood to live. The blood is brought by the arteries and carried away by the veins.
What major arteries and veins are around the heart?

Why don't you ever hear about varicose arteries?
Because arteries have vavlues to push them to the cells veins dont lol lol
