Toxicology besides focuses on parts such as the nature of toxicity, dose – response relationships, pathology and besides a constituent of Forensic Toxicology. I am speaking about toxicology is because toxicants cover a large division of toxicology.In this essay I will be chiefly concentrating how toxicants can be used as medical specialties. An illustration of a toxicant that is used as a medical specialty is Snake venom. The venom is extremely modified spit. The secretory organ that secretes the toxin, is a alteration of the parotid salivary secretory organ of other animate beings, and should normally be located on each side of the caput behind the eyes. Snake venom is a combination of many different proteins and enzymes.
