Which of the following structures is located in the pelvic cavity?

Correct Answer: C

Rationale: The correct answer is C: The bladder. The bladder is located in the pelvic cavity, specifically in the lower part of the abdomen.

The kidneys (A) are located in the upper abdominal area, the colon (B) is part of the large intestine and extends from the cecum to the rectum, and the rectum (D) is the final part of the large intestine before the anus. Therefore, the bladder is the only structure among the choices that is specifically located in the pelvic cavity.

Correct Answer: B

Rationale: The correct answer is B: To control body movement and coordination. The nervous system is responsible for receiving sensory input, processing information, and sending signals to control muscle movement and coordination. It includes the brain, spinal cord, and nerves. Choice A is incorrect as the immune system fights infection. Choice C is incorrect as metabolism is regulated by the endocrine system. Choice D is incorrect as oxygen transportation is the function of the circulatory system, not the nervous system.

Question 5 of 5

Which structure in the respiratory system is responsible for voice production?

Correct Answer: B

Rationale: The correct answer is B: Larynx. The larynx houses the vocal cords, which vibrate to produce sound for voice production. The pharynx is involved in swallowing, the trachea is responsible for air passage to the lungs, and the bronchi are the airways that branch off from the trachea into the lungs. The larynx specifically contains the vocal cords, making it the structure responsible for voice production.
