Clinicians divide the toxins by their effect on the body into three parts:
Topical toxins: They affect the tissues that come into contact with them, which affect locally when they touch the tissues of the body and have no other effect as they are not absorbed. These are called corrosives, such as concentrated acids and alkali.
The toxins that affect the physiological functions of the cells: These toxins have no local effect but their effect appears after absorption, affecting and disrupting the flow of chemical reactions such as cyanide, which prevents the cells from using oxygen and such as carbon monoxide, which converts hemoglobin to carboxy hemoglobin is not suitable for oxygen transport of tissues . Most drugs and drugs (such as opium and its derivatives) are included in this section.
Poisons affect the two ways together: They are toxins that affect the body, and affect the absorption of various body organs depending on the type of poison. This category includes most mineral salts such as arsenic, mercury and lead, and some are called poisonous toxins.
