Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The cardiovascular system is responsible for:
Correct Answer: B
Rationale: The cardiovascular system's core mission is transporting oxygen and nutrients via blood to every tissue, sustaining cellular life. Comprising the heart, arteries, and veins, it ensures vital substances reach organs while removing waste like carbon dioxide. Unlike systems focused on digestion or hormone production, its relentless circulation underpins all bodily functions. Nurses and doctors rely on this system's efficiency to support recovery and vitality, making it a linchpin in maintaining overall health.
Question 2 of 5
The urinary system is responsible for:
Correct Answer: C
Rationale: The urinary system filters blood to remove waste and maintains fluid balance through urine production. Comprising kidneys, ureters, bladder, and urethra, it's distinct from endocrine or circulatory roles, focusing on excretion and homeostasis. Nurses monitor this system to manage conditions like dehydration, ensuring bodily stability through its regulatory functions.
Question 3 of 5
What is the main difference between anatomy and physiology?
Correct Answer: B
Rationale: Anatomy maps the body's physical layout bones, organs while physiology explores how these parts work, like heartbeats or digestion. This distinction shapes medical education, with anatomy guiding surgical precision and physiology informing functional treatments. Together, they provide a complete picture, but their unique focuses ensure comprehensive health understanding.
Question 4 of 5
A transverse plane divides the body into:
Correct Answer: C
Rationale: The transverse plane cuts horizontally, separating the body into upper and lower sections, like head from torso. This perspective is crucial for cross-sectional views in scans, helping clinicians assess organs at specific levels. It's a practical tool for understanding spatial relationships in health assessments.
Question 5 of 5
The abdominal cavity contains the:
Correct Answer: C
Rationale: The abdominal cavity holds digestive organs liver, stomach, intestines processing nutrients below the diaphragm. Unlike thoracic or pelvic regions, it's a hub for metabolism. Clinicians target it for issues like appendicitis, leveraging its anatomical scope to address digestion and nutrient distribution effectively.
