GEOLOGY

Detailed explanation-1: -Pharmacokinetics, sometimes described as what the body does to a drug, refers to the movement of drug into, through, and out of the body-the time course of its absorption.

Detailed explanation-2: -In medicine, a term used to describe how a drug or other substance produces an effect in the body. For example, a drug’s mechanism of action could be how it affects a specific target in a cell, such as an enzyme, or a cell function, such as cell growth.

Detailed explanation-3: -The kidney uses three mechanisms of drug excretion: glomerular filtration, active secretion through the proximal tubules, or distal tubule reabsorption.

Detailed explanation-4: -Excretion in the bile is another significant form of drug elimination. The liver can actively secrete ionized drugs with a molecular weight greater than 300 g/mol into bile, from where they reach the digestive tract and are either eliminated in feces or reabsorbed as part of the enterohepatic cycle.
