Discuss the factors that influence the absorptionprocess for each route, and explain how the body limits the absorption of toxicants. Use specificexamples from the literature to support your response.Word Count Requirement:800-1000 words

Toxicology2AbstractAll living organisms require nutrientsand airwhich are vital for the operation andmaintenance of the body system.These substances are introduced into the body of the organismsthrough exposure which include ingestion, inhalation and skin absorption. During processes,toxicantsgets into the body by the processes among which areinhalation,ingestion andabsorption through the skin. Thoughthesetoxicants may be present in the body, their absorptionmay be limited for inhalation, ingestion and absorption. This paper will describe how toxicantsabsorption is limited for the ingestion, inhalation and absorption.INTRODUCTIONInorderfor a xenobiotic to produce a notable effect on the internal organs and sometimeexternal organs, it must be introduced into the body system throughabsorption.Absorptionis theprocedure in whichtoxicants gainaccess to the body through ingestionand inhalation of thesesubstances. After absorption, the toxicants penetrate thegastrointestinal tract or the respiratorysysteminto the deep layers and ultimately to the blood stream which transport them to differentparts of the body.(2013).Absorption of toxicants. Retrieved fromhttp://www.eoearth.org/view/article/149799Absorption varies greatly with specific chemicals and with the route of exposure. Not allthe exposure dose become the internal dose except for directlyimplanted or injected substanceswhose exposure dose also known as the outside dose has similar quantity as the internal dose.Three among other several factors affect the absorption of xenobiotics and theseare: chemical
