Final answer:
The statement is false; the rectum, not the anus, is responsible for storing feces until they can be expelled. The large intestine turns chyme into feces, and the rectum temporarily stores them before defecation, controlled by two sphincters.
Step-by-step explanation:
The statement that the anus stores feces until it can be expelled is false. In the human digestive system, it is the rectum that primarily serves to store feces until defecation. The rectum is a short part of the large intestine located between the colon and the anus. Here, feces are stored temporarily until the body is ready to eliminate them through the anus. During the process of elimination, feces are propelled using peristaltic movements.
The large intestine plays a role in absorbing water from undigested food, thereby turning liquid chyme into solid feces. Two sphincters located between the rectum and anus regulate the passage of feces: an inner involuntary sphincter and an outer voluntary sphincter. These sphincters ensure that fecal matter is expelled at an appropriate time. Thus, while the large intestine is involved in the process of storing waste until it is ready for elimination, it's the rectum that acts as the immediate storage area, not the anus.
