Antitoxins are developed during what process in the body?

Antitoxins are specifically produced by the immune system as part of the body's defense mechanism against harmful substances, particularly toxins generated by microorganisms. When the body encounters these toxins, it triggers an immune response that involves the generation of antibodies known as antitoxins. These antitoxins are designed to bind to and neutralize the toxins, rendering them harmless. This process is crucial for protecting the body from the detrimental effects of microbial infections.

The other options do not accurately describe the function of antitoxins. While enhancing breathing capacity, improving digestion, or facilitating nutrient absorption are essential bodily functions, they do not pertain to the specific role of antitoxins in neutralizing poisons.
