Hint: Since the food digestion is completed in the small intestine and almost all nutrients are absorbed here, the feces are formed in a part of the digestive tract that lies after the small intestine by the absorption of a rest amount of water.
Complete answer:
The colon is the largest part of the large intestine and serves as a site for the formation of feces. When the processes of digestion and absorption are completed in the small intestine, the remaining material passes to the large intestine that has three parts – caecum, colon, and rectum. Before reaching the colon, the digested food is essentially liquid due to the presence of water that came either through the fluid intake or as a part of the digestion process.
The colon absorbs the available water from the digested materials and leaves the remaining material in a semi-solid form that is known as stool or feces. Besides water, some salts are also absorbed in the colon before the digested material becomes ready for the elimination from the body. Each day, about 1.5 liters of water arrive in the colon and the maximum part of it absorbed here.
Note: The colon consists of six sections that are – ascending colon, caecum, appendix, transverse colon, descending colon, sigmoid colon, and rectum. The rectum is the terminal part of the digestive tract which temporarily stores feces before their elimination. This part is also absorptive as it absorbs some residual amount of water.
