Inhalation is how air and other gases get into our lungs, this provides oxygen where it is absorbed into the bloodstream. It is a vital part of human life and generally until you have problems breathing, you wouldn't notice that it is happening.Â
Inhalation is the most common way for chemicals to enter our bodies and it can happen in 3 different forms:
Gases / Vapors
Mists
Dusts / Fumes / Smoke
Something we might do to prevent inhaling hazardous chemicals is wearing a face mask.
