The diaphragm is situated between the chest cavity and the abdominal cavity.
The diaphragm separates the abdominal & thoracic (same as in people) cavities.
DIAPHRAGM divides the body into thoracic and abdomo -pelvic cavities.

The diaphragm is a thick muscle separating the thoracic and abdominopelvic cavities.
diaphragm is muscular part made up of involuntary smooth muscles.it is nothing but a thin rubber dome with a springy and flexible rim.any dividing structure is acts as a diaphragm and is called so.a number of structures acts so.in body ,THORACIC DIAPHRAGM; a tissue of muscle separating thoracic and abdomen.it also plays important role in respiration.UROGENITAL DIAPHRAGM;a layer of pelvis separating deep perineal sac from upper pelvis.PELVIC DIAPHRAGM;a pelvic muscle consisting of levator ani and coccygeus.even iris and eardrum acts as a diaphragm.even it is used in birth control.;inserted in vagina and fitted over cervix and is held in place by vaginal muscles,this diaphragm holds spermicide in place over cervix.it kills sperms and prevent fertilization.thus the diaphragm acts as a dividing structure in various parts and divides body in various parts.
The insuflation, deflation of the lungs produces great variations of pressure in the torax. If those variations were produced in a cavity including abdominal organs, some processes wouldn't take place (or could at least be not functional)
Diaphragm
In terms of body regions, the abdomen is inferior to the diaphragm. In terms of body cavities, the abdominopelvic cavity is inferior to the diaphragm. In terms of anatomical regions of the body, the umbilical region is the inferior to the epigastric region (which the diaphragm is found in)
You have two cavities related to diaphragm. But the shape of diaphragm is dome shaped and you can say that abdominal cavity is directly interior to diaphragm.
The Thoracic cavity (above the diaphragm) & the Abdominal cavity (below).
