Alcohol and human physiology
*Alcohol should always be used with caution!
When alcohol use or abuse it is important to be informed about all possible consequences, just as familiar with the medical leaflet for each drug.
Knowing how your body tolerate alcohol and how fast it processes is a good basis to take preventive measures.
When drinking a small amount of it falls directly into the blood through the mouth and throat. In the stomach, sphincter closed at 30-40% of the alcohol may be treated for 20 minutes. However, when the sphincter is opened, the alcohol enters the small intestine, where it is absorbed very quickly. Then the blood alcohol spreads throughout the body. Thus reaches the brain.
Alcohol acts as anenstetik. Its effect is similar to the ether or chloroform. It acts as a depressant on the central nervous system affecting all organ systems of the body and controls the brain. From this it is clear that the consequences of alcohol use that are losing control over your body and your actions.
Molecules of alcohol are very small and is easily dissolved in water. Even as alcohol enters the mouth and throat began its absorption and rapid absorption by simple diffusion falling in intensive vascularised organs of the body.
Unlike the fats, carbohydrates and proteins, the alcohol does not need from pre-digestion or by special “carrier”, in order to enter the bloodstream. Alcoholic beverages remain in the stomach before entering the small intestine. Absorption of alcohol can occur through the walls of the stomach, but quickly it happens through the walls of the small intestine that best absorb nutrients in the body. The surface of the small intestine is one thousand times greater than that of the stomach, their walls are much thinner and vascularized.
Usually about 30% of the commitment alcohol is absorbed from the stomach, the remaining 70% is absorbed in the small intestine. Factors that can affect the overall level of absorption include the type of the alcohol, its concentration of alcohol, sex of the person, the type of food which is taken up, the degree of dehydration of the body, how long a person ingests alcohol and so on.
All these parameters define stapenta of tolerance towards the use of Spiritus in every person.
Distribution of alcohol in the body
After the introduction of the alcohol in the blood, blood circulating in the body alcohol distributed in all body fluids and tissues. Immediately after absorption, alcohol is distributed by the blood throughout the body through the cardiovascular system and reaches various organs.
The most important and the only factor influencing the concentration of alcohol in the bodies of water content in the body. The alcohol is absorbed from the stomach and small intestine enters the portal vein, which directly led him to the liver, the main organ of detoxification. Then the blood passes through the lungs, where it is separated kosloroda, while carbon dioxide and other volatile compounds such as ethyl alcohol discarded. This process takes place in the alveoli in the deep parts of the lungs.
The number of alveoli reaches 300 million. Each socket is surrounded by a network of capillaries. In the respiratory system, the air moves backwards and forwards in the same system of conduits leading to a continuous mixing of breaths of air. Blood coming from the lungs enters the left atrium, where it falls directly into the arterial flow. Approximately one third of the total volume of blood from the left side of the heart enters the brain, while the remaining two thirds are allocated to other organs and systems. Much passes through the kidneys where it is filtered and purified.
Elimination of alcohol begins immediately after taking his body and continues until completely removed. Runoff consists of two separate processes – metabolism and excretion. Around 90-98% of the consumed alcohol is eliminated through metabolism in the body. The metabolism occurs primarily in the liver as effectively process the alcohol in the body, transforming it into other compounds. This process is performed by the enzyme alcohol dehydrogenase. The final products of this reaction carbon dioxide and water are non-toxic and leaves the body through exhalation. The combination of metabolism and excretion results in the complete removal of alcohol from the body. Specific values of the processed alcohol for one hour for each person depend on the weight and volume of adipose tissue. For a person weighing 70 kg the amount of alcohol that can be emitted from the body in 1 hour is about 25 ml of 40 percent alcohol or 10 ml of pure alcohol.
How to change human behavior after drinking?
Alcohol affects everyone! It manifests itself in different ways depending on your mood, physical and emotional condition and surroundings. If you have recently suffered, if you are sleepy, the effect of alcohol will be much stronger.
If you are experiencing personal or business problems, alcohol will increase your anxiety and can lead to aggressive or hostile behavior. The effect of the alcohol depends on the surrounding environment. Several exams drinks in drunken friendly, a company can affect you much more than the same amount consumed a business meeting.
People who use long alcohol can learn to behave in his usual way, but could not control the influence of alcohol in situations requiring motor coordination. As a result of prolonged and regular use of alcohol, the liver starts to more effectively breaks down alcohol. Furthermore, the liver is changed and brain activity – brain cells become “more sensitive.” Gradually, the body needs more and more alcohol to reach intoxication, a typical sign of early alcoholism.
Regardless of individual circumstances, there are certain symptoms corresponding to different stages of alcohol intoxication.
Firstly alcohol affects these mental processes related to education and recently pridobotite habits. One of them is the ability to drive, especially in people with little experience. Furthermore, impairs the ability to perform routine, everyday tasks that are running habit. At this stage you will find that you are able to concentrate only in opening a bottle of wine. You start missing things, and it is difficult to maintain a normal conversation with others.
If the quantities of alcohol continue to increase following the disturbances in muscle coordination and progressive suppression of basic reflexes. These include hand tremors, emotional instability and others. Drunk people can become aggressive or hostile. There is also the risk of a stupor or coma. If the coma lasted more than 10 hours, often occurs death from asphyxia caused by the respiratory center in the brain. Alcohol poisoning occurs when the concentration of alcohol in the blood is higher than 4 per mille.
