The<unk>  is a human<unk><unk>  that is in the anterior (front) aspect of the human<unk> . It is made up of the thoracic<unk> , and the abdominopelvic<unk> .  The abdominopelvic<unk>  is further separated into the abdominal<unk>  and pelvic<unk> , but there is no physical barrier between the two. The abdominal<unk>  contains digestive organs, the pelvic<unk>  contains the urinary bladder, internal reproductive organs, and rectum.
There are two methods for dividing the abdominopelvic<unk> . 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.
The second method for dividing the abdominopelvic<unk>  is preferred by anatomists. This method divides the<unk>  into nine regions. The regions are the left and right hypochondriac regions, so named because they lie under the ribs; the epigastric region which is approximately where the stomach is located between the hypochondriac regions; the right and left lumbar regions which flank the umbilical region (which surrounds the umbilicus, or belly button), the right and left iliac/inguinal regions which are where the hips are, and the hypogastric/pubic region, which lies between the hips.
The thoracic<unk>  is separated from the abdominopelvic<unk>  by the diaphragm.  The thoracic<unk>  is further separated into the pleural<unk>  which contains the lungs and the superior mediastinum which includes the pericardial (heart)<unk> .
The organs within the<unk>  are called the viscera.
