Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 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 2 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.
Question 3 of 5
The varying conditions outside the human body are sometimes referred to as:
Correct Answer: B
Rationale: The external environment, denotes variable external conditions temperature, humidity unlike internal environment (A, body fluids), homeostasis (C, stability), disease, or set points (E, targets). Anatomically, it contrasts with the regulated internal milieu, influencing adaptation (e.g., sweating), confirming B.
Question 4 of 5
To which of the following does the 'tissue level' of structural organisation refer?
Correct Answer: D
Rationale: The tissue level groups cells into specialized types muscle for movement, nervous for signaling, connective for support, epithelial for covering forming the body's functional fabrics. Above cells and below organs, it's a critical organizational tier. Nurses study these to understand how tissues collaborate in health like muscle aiding mobility or falter in disease, such as epithelial breaches in ulcers. This level's diversity drives bodily complexity, distinguishing it from cellular components or organ-specific units.
Question 5 of 5
Which of the following is/are the contents of the ventral cavity?
Correct Answer: C
Rationale: The ventral cavity, spanning chest and abdomen, contains all internal organs or viscera like the heart, lungs, and digestive tract. This collective term captures its diverse occupants, vital for life's processes. Nurses monitor these for conditions like pneumonia affecting the thoracic or abdomino-pelvic zones, distinguishing them from dorsal contents. It's a broad anatomical category, guiding holistic care for the body's front-side systems.
