ORGAN SYSTEMS AND BODY CAVITIES El< ER of the large intestine. Within the abdominal cavity is the peritoneal cavity which contains the pancreas, kidneys, adrenal glands, and portions of the large intestine, small intestine, aorta, and inferior vena cava. The pelvic cavity is the inferior portion of the abdominopelvic cavity. The pelvic cavity contains part of the large intestine, rectum, urinary bladder, female reproductive organs (ovaries, uter-ine tubes, uterus, vagina), and male reproductive organs (prostate, and part of ductus deferens). It is important to note that the testes and penis are nol located in the pelvic cavity but are located inferior to it 1s . . r1 so~ L-Ay-·'' s n ororgaannss ar aree fo found within body cavities. of the c,vu . th b . d . .
