• \Anatomical structure which has as its parts a heterogeneous collection of organs, organ parts, cells, cell parts or body part subdivisions that are adjacent to, or continuous with one another; does not constitute a cell part, cell, tissue, organ, or body part subdivision.\Structure of anatomical compartment (body structure)\Structure of body cavity and/or content\This structure comprises the space and content within the boundaries of the abdominopelvic cavity but excludes the walls that define and enclose the space. Previously SNOMED CT used the word 'compartment' to describe structures comprising the cavity and content but FMA has used the same word to include cavity, content and wall. As a consequence, the preferred notation is intra-abdominopelvic structure as this more clearly excludes the 'wall' structures. The intra-abdominopelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the thoracic diaphragm; inferiorly the pelvic diaphragm; anteriorly the anterior abdominal wall (including the lateral abdominal wall); and posteriorly the wall of the abdominal proper segment of trunk. The pelvic component consists of the cavity and content of the true pelvis, which is bounded by the pelvic wall. Note, the structures that form the boundaries are excluded.\...
• \Structure of cavity and/or content of pelvis (body structure)\This structure comprises the space and content within the boundaries of the cavity of the true pelvis (also known as the cavity of the minor or lesser pelvis) but excludes the walls that define and enclose the space. Previously SNOMED CT used the word 'compartment' to describe structures comprising the cavity and content but FMA has used the same word to include cavity, content and wall. As a consequence, the preferred notation is intra-abdominopelvic structure as this more clearly excludes the 'wall' structures. The intra-pelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the superior pelvic aperture; inferiorly the inferior aperture of true pelvis and pelvic diaphragm; and laterally the pelvic wall. Note, the structures that form the boundaries are excluded. The content includes the urinary bladder, sigmoid colon (although it is acknowledged that this is mobile and sits in a variable location), rectum, anal canal, pelvic segment of ureter and the retropubic and presacral space; the female pelvis also includes the ovaries, fallopian tubes, uterus, vagina, female urethra, soft tissues including the broad ligament and the retrouterine pouch of Douglas.; the male true pelvis also includes the prostate, male urethra, seminal vesicles, soft tissues including the pubovesical and puboprostatic ligaments and the retrovesical space.\Lower bowel structures\Sigmoid colon structure

The pelvic component consists of the cavity and content of the true pelvis, which is bounded by the pelvic wall. Note, the structures that form the boundaries are excluded.\Any organ (viscera) contained within the abdominopelvic cavity. The abdominopelvic viscera includes stomach, small intestine, large intestine, spleen, kidneys, adrenal glands, pancreas, liver and gallbladder and the viscera within the true pelvic cavity including ovaries, uterus, prostate, urinary bladder and anal canal.\Intestinal structure\Structure of large intestine (body structure)\Large intestine part\Region of large intestine\Structure of cecum and/or colon and/or rectum (body structure)\Colon structure\Colon part (body structure)\Region of colon\Left colon structure\Sigmoid colon structure
• \Body region structure\Body part structure\Trunk structure (body structure)\Structure of body cavity and/or content\This structure comprises the space and content within the boundaries of the abdominopelvic cavity but excludes the walls that define and enclose the space. Previously SNOMED CT used the word 'compartment' to describe structures comprising the cavity and content but FMA has used the same word to include cavity, content and wall. As a consequence, the preferred notation is intra-abdominopelvic structure as this more clearly excludes the 'wall' structures. The intra-abdominopelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the thoracic diaphragm; inferiorly the pelvic diaphragm; anteriorly the anterior abdominal wall (including the lateral abdominal wall); and posteriorly the wall of the abdominal proper segment of trunk. The pelvic component consists of the cavity and content of the true pelvis, which is bounded by the pelvic wall.
