<P> The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body . It is made up of the thoracic cavity, and the abdominopelvic cavity . The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two . The abdominal cavity contains digestive organs, the pelvic cavity contains the urinary bladder, internal reproductive organs, and rectum . </P> <P> There are two methods for dividing the abdominopelvic cavity . The clinical method, used by physicians and nurses, utilizes four sections called quadrants . They are the right upper quadrant, the left upper quadrant, the right lower quadrant, and the left lower quadrant . The directional terms refer to the model's right and left, not the viewer's . Clinicians use the quadrant method because in reality, organs are mobile and move around when the patient is in different positions . </P>

The thoracic cavity is superior to the abdominal cavity
