The impact of a toxic agent on the body depends on several factors, including the route of exposure, dose, and individual susceptibility. Common routes of exposure include ingestion, inhalation, and dermal contact. Once absorbed, toxic agents can cause cell damage, interfere with metabolic processes, and disrupt normal physiological functions.
For instance, carbon monoxide binds to hemoglobin, reducing the blood's oxygen-carrying capacity, while mercury can accumulate in the brain, leading to neurotoxicity.
