What is Alcohol and the Body?

Within Biology, which covers cells, the human body, genetics, evolution, plants and ecosystems: the science of living things, this topic explains Alcohol and the Body. Biology topics show how living things work, from the cell up to whole ecosystems, with models you can explore step by step.

Check that you can explain Alcohol and the Body in your own words and give one example from everyday life. If you can do that, you have understood the core idea.

Understanding Alcohol and the Body helps you explain how living things stay alive and respond to their surroundings, which is central to biology exams.

Alcohol and the Body in detail

Alcohol is a depressant that slows the nervous system, increasing reaction time and reducing judgement and coordination, so it is dangerous with driving. It is absorbed into the blood from the stomach and small intestine and broken down in the liver.

Long-term misuse can cause liver damage (cirrhosis), brain damage, heart disease, stomach ulcers and addiction, and it affects relationships and work. In pregnancy, alcohol can damage the fetus, causing fetal alcohol syndrome. Alcohol is a legal drug, but its health and social costs are large.
