How long does it normally take to process one 12-ounce beer from your system?
Darina [25.2K]

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.

The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.

Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.

For example, the digestive system digests food because of the enzymes and the cells and organs present in its system but again, this is aided by the different hormones which is part of the endocrine system, interdependently. Thus eventually, the circulatory system is the organ system that intiates in dissemination of the different processed and intially metabolized nutrients in the digestive system and sent throughout the body. Incidentally, also the immune system acts as agent in again many systems to maintain the so-called homeostasis.
