Feces, commonly known as stool or poop, is the solid waste product that is expelled from the digestive tract of humans and many animals. It is composed of undigested food, bacteria, and cells shed from the lining of the intestines. The color, consistency, and odor of feces can vary based on diet, hydration, and overall health.
The process of producing feces begins in the digestive system, where food is broken down and nutrients are absorbed. The remaining waste is then compacted in the large intestine before being eliminated through the anus. Proper disposal and sanitation of feces are important for public health, as it can harbor harmful pathogens.
