Which of these describes ethanol?

The description of ethanol as a CNS depressant and multi-system toxin accurately reflects its physiological effects and impact on the body. Ethanol primarily acts as a central nervous system depressant, which means that it slows down brain function and neural activity. This reduction in CNS activity can lead to effects such as impaired coordination, decreased reaction time, and alterations in mood and behavior.

As a multi-system toxin, ethanol adversely affects various organ systems when consumed in high quantities or over prolonged periods. It can lead to liver damage, neurological deficits, cardiovascular issues, and gastrointestinal problems, among others. Chronic exposure to ethanol can result in serious health conditions, including alcohol use disorder, liver cirrhosis, and neurological impairments. Thus, the characterization of ethanol encompasses both its depressant effects on the nervous system and its toxic impact on multiple systems within the body.
