Final answer:
The large intestine is responsible for forming solid feces from the liquid waste that comes from the small intestine, which are later stored in the rectum and eliminated through the anus.
Step-by-step explanation:
The large intestine is a crucial part of our digestive system that handles the absorption of water and salts from our food waste, ultimately forming solid feces for elimination. As digestive waste moves from the small intestine into the large intestine, it starts as a liquid mixture. This mixture enters the cecum, moves through the colon where it becomes more solid as water is reabsorbed, and solid wastes called feces are formed.
Feces then accumulate in the rectum, the final portion of the large intestine. The rectum functions as a temporary storage area for the feces, which becomes compacted as it fills. When the feces are ready to be eliminated from the body, they pass through the anus. This process is controlled by two sphincters between the rectum and the anus; the inner sphincter is involuntary and the outer sphincter is voluntary, allowing for control over the elimination.
