The urinary bladder and the internal reproductive organs are found in which cavity?

The left ventricle of the heart normally has the thickest wall, which is composed mainly of cardiac muscle tissue (myocardium). The left ventricle has to generate enough force to pump oxygen-rich blood to the rest of the body through the systemic circulation, which requires greater muscular effort than the right ventricle, which pumps blood only to the lungs via the pulmonary circulation. The thickness of the left ventricular wall ensures that it can withstand the pressure required to generate this forceful contraction.

The urinary bladder and internal reproductive organs, including the uterus, ovaries, and testes, are in the pelvic cavity. The pelvic cavity is a bony structure formed by the pelvis and contains the terminal portions of the digestive tract, urinary tract, and reproductive tract. It is situated inferior to the abdominal cavity and is separated from it by the pelvic brim, which is a rim of bone formed by the iliac crests, sacrum, and pubic bones. The pelvic cavity is bounded by the pelvic bones and the pelvic diaphragm and is lined with the pelvic peritoneum.
