What are the four main ways of being poisoned?

The correct answer identifies the four primary routes through which poisoning can occur: swallowing, inhaling, injection, and absorption through the skin. Each of these methods represents a distinct pathway by which harmful substances can enter the body.

Swallowing refers to ingesting toxins through food or liquids, making it one of the most common methods of poisoning, especially in cases involving household chemicals or medications. Inhaling involves breathing in gases, fumes, or vapors, which can quickly affect the respiratory system and spread throughout the body. Injection can occur through needle exposure or insect bites, introducing substances directly into the bloodstream, allowing for rapid absorption and potential systemic effects. Absorption through the skin involves chemicals entering the body through dermal contact, which can happen with certain pesticides, chemicals, or drugs that can permeate the skin.

The other options, while they describe various actions or sensations, do not accurately represent the main ways that poisoning occurs. For instance, drinking and eating are forms of swallowing, and touching is not specific to harmful substances. Instead, it is essential to understand the defined routes of exposure that can lead to poisoning to effectively prevent and respond to such incidents.
