The urinary bladder and the internal reproductive organs are found in which cavity?
A.
Pleural cavity
B.
Abdominal cavity
C.
Pelvic cavity
D.
Thoracic cavity
The Correct Answer and Explanation is:
The correct answer is C. Pelvic cavity.
Explanation:
The human body is divided into several cavities that house and protect different organ systems. These cavities include the cranial, thoracic, abdominal, and pelvic cavities. Each cavity serves as a compartment for various organs, separated by membranes, bones, or muscular structures.
Pelvic Cavity
The pelvic cavity is located at the lower part of the abdominopelvic cavity, below the abdominal cavity. It is bounded by the bones of the pelvis and houses the internal reproductive organs and the urinary bladder. In females, the pelvic cavity contains the uterus, ovaries, fallopian tubes, and part of the vagina. In males, it holds the prostate gland, seminal vesicles, and parts of the vas deferens. Both sexes have a urinary bladder located in the pelvic cavity, which stores urine until excretion. Additionally, the pelvic cavity contains the rectum and parts of the large intestine.
Other Cavities
- Pleural Cavity: The pleural cavity is part of the thoracic cavity, located within the chest, and houses the lungs. The pleura, a thin membrane, lines this cavity to reduce friction during breathing.
- Abdominal Cavity: This cavity lies above the pelvic cavity and contains most of the digestive organs, including the stomach, liver, pancreas, intestines, and kidneys.
- Thoracic Cavity: Found above the diaphragm, this cavity houses the heart and lungs, enclosed by the rib cage. It is further divided into the pleural and pericardial cavities (which house the lungs and heart, respectively).
In summary, the pelvic cavity specifically contains the urinary bladder and the internal reproductive organs, making it the correct answer in this context.
