- Divided into two parts: peritoneal and retroperitoneal cavities
- Upper part of peritoneal cavity contains: stomach, duodenum, spleen, liver, and gallbladder
- Lower part of peritoneal cavity contains: small and large intestines
- Retroperitoneal cavity contains: kidneys, ureters, and large blood vessels
Pelvic Cavity
- Lower extension of the abdominal cavity
- Comprises: bladder, urethra, rectum, prostate in men, and reproductive organs in females (uterus, uterine tubes, and ovaries)
