The regurgitated undigested matter in birds is called "pellet". It consists of indigestible parts of their meal such as bones, fur, feathers, and other debris that the bird regurgitates in order to cleanse its digestive system.
Feces or fecal matter is the undigested residue of the digestion process. It is also called stool, excrement, body waste, etc. There are also names specific to the species such as manure, droppings, dung, etc. It also has rude names such as poop, and a number of others that don't belong on this site.
Spleen removal is called an open splenectomy or a laparoscopic splenectomy, depending upon how it is performed.
Amoebas excrete waste through a process called exocytosis, where they expel undigested food particles and other waste materials from their cell membrane. This helps to maintain the amoeba's internal environment and prevent the accumulation of harmful substances.
Undigested waste is commonly referred to as feces or stool. It consists of the remnants of food that the body has not absorbed during digestion, along with bacteria, cells, and other substances. This waste is expelled from the body through the rectum during the process of defecation.
Feaces
ummmm.....nature's little gift of love....poop.
it helps to eject out all the waste products i.e. undigested, unabsorbed substances called faeces.
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.
Plant and animal residues are reduced to simple chemicals through the process of decomposition. This is when plant and animal residues are returned to the soil.
Defecation or elimination is the process of removing undigested food (feces) from the body.

Undigested food leaves the Paramecium through a structure called the anal pore, which serves as the organism's anus. The anal pore is located at the posterior end of the Paramecium and allows undigested food particles to be expelled from the cell.
Undigested solid waste is typically referred to as feces or stool. It is the waste material that is excreted from the body through the rectum after the digestion process is complete.
It is the removal of half of the stomach called a gastroectomy
