Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The serous membrane that lines the thoracic cavity is the
Correct Answer: B
Rationale: The parietal pleura lines the thoracic cavity's walls, unlike visceral pleura (A, lung surface), visceral pericardium (C, heart), or parietal peritoneum (D, abdominal). Serous membranes reduce friction, and parietal denotes cavity lining in anatomy.
Question 2 of 5
Identify the system that removes nitrogenous wastes from the blood.
Correct Answer: A
Rationale: The urinary system (kidneys) removes nitrogenous wastes (e.g., urea), not cardiovascular (B, circulation), endocrine (C, hormones), or digestive (D, food). Anatomically, kidneys filter blood, a key excretory role, confirming A.
Question 3 of 5
Which of the following is NOT part of a homeostatic mechanism?
Correct Answer: C
Rationale: Homeostasis involves sensors (detect), control centers (process), and effectors (act), not arteries (C, blood vessels). Arteries may be affected but aren't core components. Anatomy ties this to feedback loops e.g., thermoregulation excluding C.
Question 4 of 5
Identify a type of medical scan that places the radioactive material inside the body instead of hitting the body from the outside.
Correct Answer: D
Rationale: PET (positron emission tomography) uses internal radioactive tracers, unlike X-rays, CT, or MRI, which use external sources. Anatomical imaging benefits from PET's metabolic insight, confirming D.
Question 5 of 5
The largest hollow space in the human body is:
Correct Answer: D
Rationale: The abdominal cavity, is the largest hollow space, spanning diaphragm to pelvis, housing organs like stomach and liver. The cranial holds the brain, pelvic the bladder, thoracic the lungs, and spinal the cord all smaller. Anatomically, its expansive volume accommodates digestive and reproductive systems, justifying D over others.
