Answer 1

We can have a little, say the experts whose studies have shown in very moderate amounts vintages and brews and even hard liquor may be somewhat beneficial to the heart. (Notice all the caveats – “may be”, “somewhat.”) All bets are off, of course, for women who are pregnant – at least for those not interested in risking a baby born with fetal alcohol syndrome.

Diabetics don’t fare much better when it comes to drink. Especially in those taking insulin or diabetic medicines like the sulfonylureas and meglitinides, alcohol can bring on hypoglycemia, or low blood glucose.

Even in the relatively healthy population, though, the reason physicians discourage excessive consumption is because immoderate levels of blood alcohol place extra demands almost every part of the body. The brain comes immediately to mind. Not only does alcohol depress the central nervous system and contracts brain tissue, it destroys brain cells which do not regenerate and can lead to cognition and memory problems.

The liver is often the next stop for health care providers explaining the untoward effects of booze on the body. It’s the organ that has to break down the alcohol. And the problem is that some products generated during alcohol metabolism, like acetaldehyde, are more toxic than the alcohol itself. In addition, a group of metabolic by-products called free radicals can damage liver cells and promote inflammation, impairing vital functions such as energy production. If that’s not enough, the body's natural defenses (like antioxidants) against free radicals can be inhibited by alcohol consumption. This sticky wicket leads to more liver damage and a vicious cycle that places bodies in direct line for nasty things likes hepatitis and cirrhosis among other ailments of the liver.

Heavy drinking and stroke are close bed-fellows as well, linked by alcohol’s tendency to cause high blood pressure (or hypertension) and a fast, irregular heart beat. High blood pressure puts a strain on the blood vessels, which can lead to the narrowing of arteries and the formation of blood clots. Hypertension is the single most important risk factor for stroke. More, a fast, irregular heart beat can cause erratic blood flow, which may lead to the formation of a blood clot. The danger is that clots can break loose and lodge themselves in the small vessels that supply the brain, blocking blood flow and causing one of the most dreaded of all conditions – stroke.

Irregular heart rate, hypertension, and blood clots are also hard on the heart, causing attacks and coronary disease. Further, since alcohol is a diuretic it increases urine output, making the kidneys work overtime. Thus, kidney failure can be a consequence of prolonged abuse of alcohol. The list goes on – inflammation of the stomach lining, cancers of the esophagus, pancreatic problems, infertility, impotence and menstrual irregularities and the often unmentioned depression.

Quite the litany of complaints against both alcohol and tobacco. The good news is that we live in an era in which people increasingly realize they must take responsibility for self care. Between that willingness and knowing some of the science behind our physicians’ admonishments, the admittedly bitter pill of having to change habits can go down a bit easier. And once we do, that glass of red or the rich dark porter will truly be a guilt-free pleasure.

Answer 2

. Venous blood containing alcohol reaches liver and to lungs .

In human anatomy, the hepatic veins are the blood vessels that drain de-oxygenated blood from the liver and blood cleaned by the liver (from the stomach, pancreas, small intestine and colon) into the inferior vena cava.

They arise from the substance of the liver, more specifically the central vein of the liver lobule.
The Portal vein also carries blood from digestive system to liver.In liver the blood and contents like drugs and alcohol are metabolised. And this purified blood also enters the hepatic veins which open into inferior vena cava.
Inferior vena caval blood reaches the heart and from heart to lungs.
Ultimately lungs secrete the unmetabolised part of alcohol and metabolised part as acetaldehyde into bronchi to be exhaled.

Answer 3

When alcohol gets into the veins, its widens them causing more blood to flow through them then normal. It can give you a headache or make you lose body heat. That's why if you are intoxicated you can't get a piercing or a tattoo because you will tend to bleed a lot more than normal.

Answer 4

I believe it poisons the blood stream. Then your liver has to filter all the toxins out of your blood stream. Heavy drinkers and alcoholics usually have bad livers because these large ammounts of toxins, over time, damage the liver.
