An Excretion must have unwanted products put into it. Like urine has urea put into it in the nephron. Or the air expired from the lungs have CO2 put into it from the blood. Feaces on the other hand has simply passed through the digestive tract and not been absorbed but importantly has not had anything added to it. So nothing in it is removing the products of any reaction. Now that I've started this is actually quite hard to explain but if I have'nt explained it well enough, feel free to email me.

What are the Distinguish between excretion and egestion?
egestion is the removal of undigested food from the gut while excretion is the process of eliminating waste products of the metabolism and other other non-useful material.
What is the difference between excretion and defecation?
The difference between excretion and defecation is excretion is the removal of waste and defecation is the removal of undigested waste. During defecation, the nutrients are absorbed by the body before being removed from the body.
Is excretion best described as the removal of undigested material from the digestive tract?
no, metabolic waste from a cell is the answer
Are excretion and defecation the same thing?
Pooping or Defecating is not excretion.Excretion is the removal of waste products of metabolism from the body. This is done by the excretory organs. (Skin, Lungs, Kidneys)Defecation (or egestion) is the removal of undigested food from the gut, it is not regarded as excretion because the material taken into the gut through mouths is not made by the body its and has not been absorbed into the cels or taken part in metabolism.The only excretory product in faeces is bile pigments.
What is removal of undigested and unabsorbed solid residues of food from the body called?
Bile
Why removal of undigested food is called excretion?
Any cell-metabolism related waste product can be loosely classified as excreta. But undigested food,which is a part of faecal matter, should not be called as excreta. However, faecal matter contains a very small amount of salts of heavy metals like Mercury,Lead etc. which are produced by cell metabolism. So faecal matter can loosely be classified as excreta.
What is the removal of metabolic wastes?
Excretion!:)
The removal of wastes fron an organism is called?
The removal of waste from an organism is called excretion.
Removal of waste products in the body is called?
The removal of waste products from the body is called excretion
Distinguish between egestion and excretion?
Egestion is the discharge or expulsion of undigested material (food) from a cell in case of unicellular organisms, and from the digestive tract via the anus in case of multicellular organisms. It should not be confused with excretion, which is getting rid of waste formed from the chemical reaction of the body, such as in urine, sweat. Egestion:- Removal of undigested food or faeces from the gut. In most animals egestion takes place via the anus, although the invertebrate flatworms must use the mouth because their gut has no exit. Egestion refers solely to indigestible matter which is never absorbed into the cells - it should not be confused with excretion of the waste products of metabolism. Excretion is the transfer of substances out of a living organism into its environment. At its simplest, for single-cell forms of life, this involves extrusion across the cell membrane of the unwanted or potentially toxic by-products of respiration and metabolism. This is also what is happening continually in the individual cells of the animal body, but from their immediate environment substances must move into the blood to be carried away to the site of their ultimate disposal. In the animal body there is also another type of excretion: expulsion of the residue of substances which have not been absorbed into the body proper from the gut (which can be considered a tunnel through the body of the external world).
Elimination (-3x-15y=-17) and (-x+5y=-13)?
Elimination is the removal of undigested food (solid waste) from the body.
Living thing remove waste from their body by the process of?
Many people confuse the process of excretion with the removal of waste products of digestion. Excretion, however, is actually the removal of all the waste products produced by the cells of the body.
