Alcohol En El Organismo

Alcohol isn't in the mouth for very long, so the enzymes that begin to break it down don't have much time to do their work. While a little is digested, most of your drink passes on to the stomach.
Mouth

Alcohol is broken down by two classes of enzymes. The first is more prevalent in the stomach and converts ethanol, the alcohol we drink, into acetaldehyde. Acetaldehyde is toxic, so the secondstep of metabolism, which occurs in the liver, happens very quickly in most people.
Alcohol will pass more slowly through the stomach if you've eaten recently, allowing for more of it to be broken down before it reaches the liver, so eating before or while drinking really does slow down your buzz. And that's a good thing! Alcohol irritates the lining of the stomach, which can bring on nausea orvomiting.
Famished? That drink is also tricking your stomach to think it's receiving fuel, as alcohol is high in calories but doesn't provide any real food, which might explain why some people feel compelled to eat while intoxicated, or are especially hungry the next day.
Stomach

The liver is responsible for breaking down most of the alcohol (now in the form of acetaldehyde) in the secondstage of metabolism. Here, the second class of enzymes converts the toxic acetaldehyde into harmless acetate, which is close in chemical makeup to vinegar.
The liver can only metabolize a certain amount of alcohol per hour, no matter how much you've actually had. So why does it seem like some people can drink more than others? This rate varies between individuals, and is also affected by gender andhow much you've had to eat that day. Plus, certain groups of people seem to have particularly low-functioning enzymes or lack the enzymes altogether, inhibiting the completion of this second phase of alcohol metabolism (this is commonly seen in the Asian population). When this happens, acetaldehyde accumulates, causing symptoms like rapid pulse, sweating, flushing, nausea and vomiting.
LiverAfter a couple of drinks, some may experience a rapid or irregular heartbeat. Researchers aren't entirely sure as to why this happens, but alcohol seems to directly affect our internal timekeeper. People who don't drink regularly are more susceptible to this kind of reaction.
Heart

Hot around the collar? Alcohol is what's called a vasodilator, meaning it naturally enlarges the blood vessels,which can make your cheeks rosy and give you that warm and toasty "beer blanket" feeling.
Circulatory System

The immune system has two parts: One works to ward off sickness and the other fights off germs once they are already present. Because alcohol suppresses both, you are left not only more susceptible to illness, but also less able to fight it. This effect lingers for about 24 hours afterthrowing a few back.
Immune System

The body normally releases a hormone called vasopressin, which, when alcohol is not present, sends water back into the body. But alcohol suppresses this hormone, and sends that water to the bladder instead, which, in turn, sends you to the bathroom line!
Kidneys

In addition to the redirected water coming to the bladder from the kidneys, alcohol is also anatural diuretic, meaning it causes cells to shrink, thereby pushing water out from each cell. To manage that extra fluid, the organs secrete it to the bladder, which gives you the urge to go to the bathroom.
Although many people feel like after that first trip to the bathroom, the need to go only increases -- a phenomenon often referred to as "breaking the seal" -- this sensation is mostly anillusion. That "seal" is really just a threshold -- after a number of drinks you can't hold it any more. As you continue drinking, you're taking in more fluids and suppressing the release of more vasopressin, leading to more frequent trips to the bathroom.

Because of the suppression happening in the frontal lobes, some people may find themselves feeling more in the mood for sex after a...
