Study Notes

Toxicology Overview

Toxicology is the scientific study focused on poisons and their effects on living organisms.
Poisons are defined as chemical or physical agents that cause harmful responses in biological systems.
Toxicity is determined by dosage; any substance can be harmful if administered in amounts that disrupt normal bodily functions.

Toxicants: Refers to toxic substances deriving from human-made chemicals.
Toxins: Poisonous substances produced naturally within living organisms and cells.
- Example of a toxin includes venom produced by certain animals.

Overview of Toxicology

Toxicology is the scientific study of poisons and toxic substances.
Focuses on various aspects, including sources, properties, mechanisms of toxicity, toxic effects, detection, clinical manifestations, and management.

Sources of Toxic Substances

- Predominantly includes pharmaceuticals and corrosive substances.
Plant Sources:
- Includes substances derived from plants, such as hashish and cocaine.
Animal Sources:
- Less common but can be more dangerous; includes venom from scorpions, spiders, snakes, and wasps.

Venomous versus Poisonous Animals

Venomous animals have the capability to deliver or inject venom into other organisms.
