Ingestion refers to taking a substance into the body through the mouth, which is a common route for many types of poisons, including medications, chemicals, and foodborne toxins. Inhalation involves breathing in substances that can cause harm, such as fumes or gases, which can quickly affect the respiratory system and enter the bloodstream. Absorption occurs when poisons make contact with the skin or mucous membranes, allowing them to penetrate the body through the dermal layers. Injection is a method where substances are introduced directly into the bloodstream via needles or other means, leading to rapid systemic effects.

The other choices include terms that are not standard methods for poisons to enter the body. For instance, “impaction” typically relates to a blockage rather than a route of poisoning, while “osmosis” is a biological process concerning the movement of water across cell membranes and is not directly related to poisoning methods. Additionally, “indigestion,” while relevant to the gastrointestinal system, is not a correct term for the process of poisoning by ingesting harmful substances and is more associated with digestive issues. The accurate understanding of these four routes is crucial for
