Absorption into the Body • Step 1- Mouth • Step 2 – Esophagus • Step 3 – Stomach (Small amount of alcohol is absorbed into mucus membranes of the stomach lining) • Step 4 – Small Intestines – Most absorption into blood stream takes place from small intestines.
Absorption • Depends on how quickly the stomach empties into intestines. (Food in stomach or empty stomach) • Gender – Females contain less body water to dilute alcohol. As a result, females become impaired more quickly. • ADH enzyme in stomach metabolizes alcohol and impedes it’s effects. Therefore, the largest portion of alcohol reaches blood stream from small intestines.
