Final answer:
Large volume stools indicate an issue with the large intestine, the organ responsible for removing water and salts from food waste and forming solid feces. Feces is composed of undigested food residues, unabsorbed digested substances, bacteria, old epithelial cells, inorganic salts, and water.
Step-by-step explanation:
The large volume of stools indicates an issue with the large intestine, which is an organ of the digestive system. The large intestine removes water and salts from food waste and forms solid feces for elimination. It stores feces until it leaves the body during defecation.
The large intestine absorbs most of the remaining water from the chyme residue, converting it into semisolid feces. Feces is composed of undigested food residues, unabsorbed digested substances, millions of bacteria, old epithelial cells, inorganic salts, and enough water to facilitate smooth elimination.
In some cases, a large volume of stools may indicate a medical condition such as diarrhea or malabsorption, which can affect the absorption of water and result in increased stool volume.
