Excretion is the biological process by which an organism separates waste products from its body. The waste products are then usually expelled from the body by elimination.
Excretion
(Science: nephrology) The act, process or function of excreting.
Origin: L. Excretio ...
EXCRETION IS NOT ELIMINATION
The excretory system is very important to your body and only has a few parts. In a similar way to removing solid waste from your body, you must also get rid of fluids.
excretion The process of removing the waste products of cellular metabolism from the body.
excretion
The disposal of nitrogen-containing waste products of metabolism.

[edit] Excretion of waste products
The kidneys excrete a variety of waste products produced by metabolism, including the nitrogenous wastes: urea (from protein catabolism) and uric acid (from nucleic acid metabolism) and water.
excretion of large amounts of a watery urine (as much as 30 liters — about 8 gallons — each day!)
unremitting thirst.
It can have several causes: ...
ureotelic excretion Having urea as the chief excretory product of nitrogen metabolism; occurs in mammals.
ureter The tube which conveys urine from the kidney to the bladder.
urethra The tube from the urinary bladder to the exterior in both sexes.
honeydew. An excretion from insects, such as aphids, mealybugs, whiteflies, and soft scales, consisting of modified plant sap.
From the preceding account of the circulation of the blood in the fetus the following facts will be evident: (1) The placenta serves the purposes of nutrition and excretion, receiving the impure blood from the fetus, ...
The flame cell system functions in excretion and consists of a series of interconnecting canals that run length of the body on either side of the longitudinal axis and side branches of the canals, each ending in a flame cell.
The cell must perform many functions including the intake of nutrients, the metabolism of those nutrients, growth, cell division, and the excretion of wastes. What molecules are involved?
These include the intake of nutrients (digestion in us), respiration or gas exchange, excretion (ridding the body of toxic wastes), coordination of actions (nerves and glands), movement (use of muscles in animals) and reproduction.
Detritus/leaves from plants/excretion from animals/dead animals
Broken down by saprotrophs/decomposition
Releases ammonia/ammonium ions (from decay)
Ammonia dissolves in H2O → NH3 + aq → NH4+ ...
Dissolved organic matter. Dissolved molecules derived from degradation of dead organisms or excretion of molecules synthesized by organisms
Disturbance. A rapid change in an environment that greatly alters a previously persistent biological community ...
and liver microsomes, an electron-transport chain in which the terminal component is cytochrome P450; this system plays a role in the detoxification of foreign substances by altering them to increase their solubility and facilitate excretion.
