What is the process called that makes a substance nonpoisonous in the human body?

The correct answer is detoxification. This process refers to the body's mechanisms for removing or neutralizing toxins and harmful substances, rendering them nonpoisonous and safe for excretion. Detoxification can occur in various organs, particularly in the liver, where enzymes convert toxic substances into less harmful compounds. This is a crucial function as it helps to maintain overall health and balance within the body by preventing the accumulation of harmful materials.

Detoxification encompasses several pathways and can involve both water-soluble and fat-soluble substances. The effectiveness of the detoxification process allows the body to manage the intake of potentially harmful substances, whether they come from food, drugs, or environmental toxins. Understanding this process is fundamental in fields related to substance use, addiction, and overall health management.
