Quizplus · Accepted Answer

The anus is the body opening that serves solely as the exit for wastes from a complete digestive tract. The cloaca is a common opening for the digestive, urinary, and reproductive tracts in some animals. The rectum is the final section of the large intestine where feces is stored before elimination. The digestive tract is the entire tube-like structure of the digestive system, including the mouth, esophagus, stomach, and intestines. The digestive cavity is the internal space where digestion occurs in certain animals, such as cnidarians.
