colon
The waste eliminated through the opening is called excrement or feces, which is the solid or semi-solid remains of food that has been digested and processed by the body. This waste is expelled through the rectum in humans and many animals, as part of the digestive system's function to remove undigested material and toxins from the body.
The typical manner is to excrete solid waste material through one's anal sphincter. The matter is typically digested plant fibers or animal flesh.

The organ responsible for reabsorbing water and leaving solid waste is the large intestine, or colon. As digested food moves through the colon, water is absorbed back into the bloodstream, while the remaining material is compacted into feces. This process helps the body retain necessary fluids while eliminating waste. The solid waste is then expelled from the body through the rectum.
The large intestine is responsible for reabsorbing excess water from digested food material. As the material passes through the large intestine, the water is reabsorbed, forming more solid waste known as feces.
Responsible for the final stages of the digestive process, the colon’s function is threefold: to absorb the remaining water and electrolytes from indigestible food matter, store food remains that were not digested in the small intestine and to eliminate solid waste (feces) from the body. Taking back the water here helps keep the water balance in the body.
The material that remains after reabsorption in the kidney is urine, which contains waste products, excess ions, and water that were not reabsorbed back into the bloodstream.
A cow defecates the remains of what she has eaten a number of hours ago, which is waste and excess matter that could not be digested or has been digested and there's nothing left to glean from in her digestive tract.
The organ in the body that absorbs more water is the large intestine. It reabsorbs water from the digested food material coming from the small intestine, helping to form solid waste (feces) before elimination.
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.
