Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
