Which of the following correctly describes how alcohol is absorbed into the blood?

Alcohol is absorbed into the bloodstream primarily through the stomach and small intestine. When consumed, alcohol travels through the digestive system and begins to absorb into the blood directly through the stomach lining. However, the majority of absorption occurs in the small intestine due to its larger surface area and rich blood supply, which facilitates the quicker transfer of alcohol into the bloodstream.

This absorption process means that when considering how the body responds to alcohol consumption, both the stomach and small intestine play crucial roles. The presence of food in the stomach can influence this absorption rate, making it slower, while consuming alcohol on an empty stomach can lead to more rapid absorption.

Thus, the choice that correctly identifies the sites of absorption of alcohol into the blood reflects this dual involvement of the stomach and small intestine.
