Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The cavity that contains the pericardial and pleural cavities is the ___ cavity.
Correct Answer: C
Rationale: The thoracic cavity contains pericardial (heart) and pleural (lungs) cavities, within the ventral cavity, but not dorsal. D overcomplicates; C is precise. Anatomically, thoracic defines the chest's subdivisions, key for understanding organ placement.
Question 2 of 5
A small child states that their stomach hurts but points to their umbilical region. Most likely the pain is originating from the:
Correct Answer: C
Rationale: The umbilical region centers on the small intestine, not liver (A, upper right), gallbladder (B, right), or stomach (D, upper left). A child's vague stomach' pain often reflects intestinal issues, common anatomically in this area.
Question 3 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 4 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 5 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.
