Metabolism is the biochemical process by which the body converts food and substances into energy and building blocks for growth, repair, and maintenance of tissues. It encompasses two main pathways: catabolism, which breaks down molecules to release energy, and anabolism, which builds complex molecules from simpler ones. Excretion, on the other hand, is the process by which waste products and excess substances are eliminated from the body, primarily through organs like the kidneys, liver, and lungs, ensuring the maintenance of homeostasis and overall health. Together, metabolism and excretion are vital for sustaining life and optimizing bodily functions.
Excretion is the term used to describe the removal of waste products of metabolism from the body.
The five basic stages of pharmacokinetics are absorption, distribution, metabolism, excretion, and elimination. Absorption refers to the movement of a drug into the bloodstream, distribution is the spread of the drug throughout the body, metabolism involves the conversion of the drug into metabolites, excretion is the removal of the drug or its metabolites from the body, and elimination is the combination of metabolism and excretion.
excretion
The word equation for excretion can be summarized as: "Metabolic waste products + Water → Urine." This process involves the removal of waste substances produced during metabolism from the body, primarily through the kidneys, and their excretion in urine.
Living organisms exhibit characteristics such as organization, metabolism, growth, adaptation, response to stimuli, and reproduction. These features help define life and differentiate living organisms from non-living entities.
The absorption, distribution, metabolism and excretion of drugs are the primary four parameters of pharmacokinetics.
The principal nitrogen excretion product of metabolism in humans is urea. It is produced in the liver as a way to remove excess nitrogen from the body, which is generated during protein metabolism. Urea is then excreted by the kidneys in the urine.
'Excretory' often refers to excretion and the Excretory System. Excretion is 'process of eliminating waste products of metabolism and other non-useful materials'1.1Beckett, B. S. (1986). Biology: A Modern Introduction. Oxford University Press, 110. ISBN 0199142602.
True
Excretion is the term used to describe the removal of waste products of metabolism from the body.
By definition Pharmacokinetic is the branch of pharmacology deals with the liberation, absorption, distribution, metabolism and excretion of drugs. absorption, distribution, metabolism and excretion of drugs are primary four parameters of pharmacokinetics.

excretion
Digestion, excretion, respiration, ingestion, and circulation.
How quickly a drug clears from the body is a function of its absorption, bioavailability, distribution, metabolism, and excretion properties.
