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.

Means the act or practice of penetrating a vein by needle for the purposes of collecting blood samples for laboratory tests as a diagnostic measure or blood donation by an individual to a blood bank, to later be used on patients needing blood suplementation.Venipuncture is used to collect samples of a patients' blood so that it's chemical composition can be tested to determine the cause of a specific illness or condition. Some of the most common tests performed daily are:1. Blood cell count2. Amount of protein, calcium, potassium, and/or glucose present3. Determine the amount of cholesterol in the blood5. Determine BAC (blood alcohol content),6. Determine the amount of oxygen in the blood and many, many more.If alcohol is injected straight into a vein?
Pharmaceutical grade ethyl alcohol is sometimes given IV. Other than the obvious problems of getting drunk (perhaps dangerously so) the alcohol is not a problem. Using alcohol that is not intended for IV use may cause problems from the other contaminants in it.
Why do they put dye through your veins?
Medical procedures involving the use of "dye" through your veins enables the veins to show up more clearly when scanned by a CT/MRI machine, or similar. This is useful when assessing levels of blood-flow around the body, and will show up where any "blockages" may be occurring.
Similar procedures involve ingesting (swallowing) a small amount of "dye"; this type of process would be used to assess the stomach, small intestine and colon.
Usually the "dye" is actually a non-harmful radioactive substance, as opposed to a liquid of a concentrated colour (which is how most people consider "dye"). It is completely harmless, and breaks down within a few hours of being injected.

When muscles contract blood is forced through what?
Blood moves from the capillaries and into the veins.
What is smooth muscle and valves?
Smooth muscles are involuntary muscles, muscles that you can not control, and are located in your organs like your stomach and intestines.
Valves are located in your heart and they are like little doors that allow the blood to flow into the chambers when open and stop the flow when closed.
What percent of blood volume loss is necessary for significant vital sign change?
Losing around 20% of your blood volume will put you into shock.
NB: When your blood pressure falls, your body is unable to compensate through the normal mechanisms of control (such as the renin-angiotensin system in the kidneys, or constricting blood vessels) for the the loss of blood and the patient is in serious shock. If the blood loss is acute, the BP may rise initially due to the constriction of blood vessels etc.
I suppose technically your estate "owns" your body to the extent that anyone does. There are laws regarding the disposal of human remains (they're basically health codes), but none of them specify that you have to give "a bunch of money" to anyone in particular. For example, cremation may be a cheaper alternative to interment, and no law anywhere that I'm aware of says you have to be embalmed or have a fancy casket (in fact, whether you need a casket at all depends on the rules of the particular cemetary you're being buried in, and federal law explicitly states that funeral homes not allowed to require that people purchase a casket from them or any other specific source).
You generally can't just have your friend Joe dig a hole in your back yard and dump you in it, though; laws specifying that human remains may only be interred in "established cemetaries" are fairly common.
If you're really going for cheap disposal, you could consider donating your remains to a nearby medical school. Most schools will cover the cost of cremation once they're "done" with the remains in exchange for you letting the school "borrow" them.
By law, who "decides" what happens to your body after you're dead is something like:
State and local government are allowed to make restrictions consistent with public health and safety concerns (for example, to say that your family can't just wrap you in a flag and dump you in the river, or grind you up and turn you into sausages).
After that, it would normally follow a "next-of-kin" order of precedence: your spouse, your adult children, your surviving parent(s), your siblings, and so on (the exact order may vary, but the spouse if you have one is almost always first).
If you've made specific provisions in your will, they may (or may not) supercede the wishes of family members. An estate planner will be better able to advise you on what the law is in your area and what's likely to be challenged (or not).
Bright red blood that spurts out comes from severed vein or severed artery?
It comes from an artery. Arteries carry OXYGENATED blood away from heart. This oxygenated blood is bright red. The Arterial system is on the high pressure side of the heart. The pressure changes as the heart contracts and then expands and refills (a heartbeat). When an artery is punctured the blood will spurt with every heartbeat.
Do you start CPR if the jugular vein is cut?
No. Stop the bleeding first, although death is almost certain and very quick if the jugular vein is severed.
What is the basic difference between arteries and veins?
Arteries carry oxygenated blood from the heart and veins carry de-oxygenated blood back to the heart.
