After being formed at the base, the new cells migrate upwards and out of the crypt, maturing along the way. Eventually, they undergo apoptosis and are shed off into the intestinal lumen. [4] In this way, the lining of the intestine is constantly renewed while the number of cells making up the epithelial layer remains constant. [5]

Human feces (American English) or faeces (British English), commonly and in medical literature more often called stool, [1] are the solid or semisolid remains of food that could not be digested or absorbed in the small intestine of humans, but has been further broken down by bacteria in the large intestine.
The result can be impaired nutrient absorption, excessive water and mineral loss through the stools due to breakdown of the control mechanisms in the intestinal tissue that normally remove water from the stools, and in severe cases, the entry of pathogenic organisms into the bloodstream. Anemia may also arise due to the blood loss through diarrhea.

[4] In fact, they are not actual parasites, but instead fragments of mucous membrane shed from the gut following the use of bleach enemas (usually marketed as Miracle Mineral Supplement) and other similarly ineffective and toxic cleanses ...

[1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [3]
