Defecation or elimination is the process of removing undigested food (feces) from the body.
ummmm.....nature's little gift of love....poop.
Fish poop is scientifically called "feces" or "excrement." It is the waste material produced by the digestive system of fish and contains undigested food particles and other waste products.
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.
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.
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.
The large intestine and rectum are responsible for excreting undigested food in the form of feces. These organs absorb water and nutrients from the food, leaving behind waste products that are then expelled from the body.
The absorption of excess water from waste and the compaction of any undigestible material (fiber) into feces occurs in the large intestine, which is also called the colon.
The lower opening of the digestive tract is called the anus. It is where waste material from the body is expelled during the process of defecation.
Feaces
Feces that are passed out of the body are called stool. This waste material is composed of undigested food, bacteria, and other substances that the body has processed. The process of expelling stool is known as defecation.
Excretion: Excretion is the process of eliminating waste products of metabolism and other non-useful materials. In humans, the two major excretory processes are the formation of urine in the kidneys and the formation of carbon dioxide (a human's abundant metabolic waste) molecules as a result of respiration, which is then exhaled from the lungs. These waste products are eliminated by urination and exhalation respectively Defecation: Defecation is the final act of digestion by which organisms eliminate solid, semisolid or liquid waste material (feces) from the digestive tract via the anus. Humans expel feces with a frequency varying from a few times daily to a few times weekly. Waves of muscular contraction known as peristalsis in the walls of the colon move fecal matter through the digestive tract towards the rectum. Undigested food may also be expelled this way; this process is called egestion. More simply: Excretion is the disposal of nitrogen-containing waste products of metabolism. Elimination (same as Defecation): is the passing of undigested materials out of the digestive compartment.
