How Are Chemicals Transported in Biological Systems?
Within biological organisms, chemicals are transported through mechanisms such as absorption, distribution, metabolism, and excretion. Absorption occurs when chemicals enter the body, typically through the skin, lungs, or gastrointestinal tract. Once absorbed, chemicals are distributed through the bloodstream to various tissues. Metabolism involves the transformation of chemicals into different forms, which can be more or less toxic. Ultimately, excretion removes chemicals from the body through urine, feces, or respiration.
