What are feces?

Feces refer specifically to the solid waste that is expelled from the digestive system after the body has absorbed the necessary nutrients from food. This waste is primarily composed of undigested food matter, bacteria, cells shed from the lining of the intestines, and various secretions. The proper terminology emphasizes that feces are a crucial aspect of the body’s waste elimination process, indicating the end of digestion. In contrast, the options related to liquid waste or components of blood plasma do not describe feces, as these pertain to different bodily functions and processes. Therefore, recognizing feces as solid waste is fundamental in understanding human biology and waste management.
