chest boundaries:
Anterior
The sternum and ribs
chest boundaries:

the 9 regions of the abdomen are:
Right hypochondriac region Epi-gastric region Left hypochondriac region Right lumbar region Umbilical region Left lumbar region Right iliac region Hypo-gastric region Left iliac region
the abdomen contains the:
Stomach Duodenum Small intestine Large intestine Pancreas Gall bladder Liver Spleen Kidneys Ureters Major blood vessels
abdomen boundaries:
Superior

Continues with the pelvis
abdomen boundaries:
Anterior
The large abdominal muscles
abdomen boundaries:
Posterior
The Lumbar vertebrae and posterior abdomen wall
abdomen boundaries:
Lateral

the pelvic cavity is:
the area of the abdomen contained within the pelvic girdle. It is continuous with the inferior boundary of the abdomen
the pelvic cavity contains the:
Bladder
Urethra
Reproductive organs
Rectum
position of major organs:
Stomach
The stomach lies in the epigastric, Umbilical and left hypochondriac regions of the abdomen. It is partly protected by the lower ribs on the left side.
position of major organs:
Liver
The liver occupies the right hypochondrium and the greater part of the epigastrium. The superior border is immediately beneath the diaphragm, extending medially as far as the stomach. The right lateral border extends to the level of the tenth rib.
position of major organs:
Spleen
The spleen lies in the left hypochondriac region of the abdomen. It lies between the stomach and the diaphragm.
position of major organs:
Kidneys
The kidneys lie in the right and left lumbar regions
position of major organs:
