The urinary bladder is not well supplied with circulating blood. Thus, alcohol is absorbed from it slowly. The absorption of ingested alcohol can be prolonged by dilution. Up to a concentration about 30 percent volume, the rate of absorption increases with concentration. Food in the stomach also slows absorption resulting in a lower peak concentration of alcohol in the blood.
Alcohol is soluble in water in all properties.
It is only slightly soluble in other body constituents. Therefore, alcohol is distributed throughout the body in body water. Those portions having the highest concentration of water will have the most alcohol when distribution is complete. Completion of uniform distribution takes 1 to 2 hours. Alcohol will leave the blood in the lungs and become part of the expired breath.
