What is the primary function of the liver regarding toxins?

The primary function of the liver regarding toxins is indeed to break down fats and filter toxins. The liver plays a crucial role in detoxification, metabolizing various substances in the body, including drugs and alcohol. It does this by converting these potentially harmful substances into less toxic forms or even making them water-soluble so they can be easily excreted from the body through urine or bile.

In addition to detoxification, the liver is responsible for the metabolism of fats, even though that is not its sole function. By breaking down fatty acids and converting them into energy or other compounds, the liver is instrumental in maintaining a balance of nutrients and energy levels in the body. This dual role of metabolizing fats and removing toxins is vital for overall health.

Although aspects from the other choices mention important functions related to the liver, they do not encompass the liver's critical role in detoxifying and filtering out toxins. For example, while the liver does produce hormones, this is not its primary function regarding toxins. Storing digestive enzymes is also not a direct role of the liver when it comes to processing harmful substances, and regulating blood pressure is primarily managed through other mechanisms in the body rather than through liver function.
