An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
Most of the liver would be found in the ___ of the abdominopelvic cavity.
Correct Answer: C
Rationale: The liver predominantly lies in the right hypochondriac region (upper right), not lumbar (A, mid), iliac (B, lower left), or hypogastric (D, lower center). This anatomical mapping aids in clinical localization, like liver palpation.
Question 2 of 5
The relative consistency of the body's internal environment is called
Correct Answer: C
Rationale: Homeostasis maintains internal stability (e.g., temperature), not hemostasis (A, clotting), regulation (B, broad), or systemic (D, body-wide). Anatomy and physiology emphasize this balance, critical for survival, confirming C.
Question 3 of 5
Identify a body imaging method that may not be used on patients with metal in their bodies.
Correct Answer: A
Rationale: MRI (magnetic resonance) is contraindicated with metal due to magnetic interference, unlike PET (B, positron), X-Ray, or CAT (D, CT). Anatomical imaging safety relies on this distinction, making A correct.
Question 4 of 5
Which directional term means 'towards the middle' of the body?
Correct Answer: C
Rationale: Medial, means toward the body's midline e.g., the nose medial to the ears. Lateral is away from midline, proximal closer to attachment, superior above, and inferior below. In anatomical position, medial orients structures centrally, critical for describing symmetry and proximity, like heart medial to lungs, making C accurate.
Question 5 of 5
The fluid portion of blood is called:
Correct Answer: C
Rationale: Plasma , is blood's fluid portion, comprising water, proteins, and electrolytes, excluding cells like platelets. Interstitial and tissue fluid surround cells, intracellular is within. Anatomically, plasma (55% of blood) carries nutrients and waste, critical for circulation, making E the precise term.
