Fecal matter refers to excrement or waste products from the body. It is a scientific term that describes any solid, liquid, or gaseous waste produced by an animal's digestive system as it breaks down food particles. This includes not only urine and feces but also other substances such as mucus, skin cells, and bacteria. In human beings, fecal matter is typically composed of undigested food residues, dead skin cells, and bacteria from the colon. It can contain parasites or pathogens that are transmitted through contaminated water, soil, or food, which makes proper disposal and sanitation important for public health.
