Q&A | Portage Learning
1. Which statement accurately describes the relationship between anatomy and
physiology?
A) Anatomy studies function, while physiology studies structure
B) Anatomy studies structure, while physiology studies function
C) Both anatomy and physiology study the structure of body parts
D) Anatomy and physiology are unrelated fields of study
Correct Answer: Anatomy studies structure, while physiology studies function
Rationale: Anatomy is the study of the structure of body parts and their relationships to
one another, derived from the Greek word meaning "to cut apart." Physiology is the study
of how the body and its parts function and carry out life-sustaining activities. The two
disciplines are complementary because structure determines function.
2. What is the principle of complementarity?
A) The body's tendency to maintain internal stability
B) The study of tissues under a microscope
C) The concept that a structure's shape determines its function
D) The breakdown of molecules for energy
Correct Answer: The concept that a structure's shape determines its function
Rationale: The principle of complementarity states that the function of a body part is
always related to its structure. For example, bones are hard and rigid because they
provide support and protection, and heart valves prevent backflow because of their one-
,way design. This principle is fundamental to understanding how anatomy and physiology
are interconnected.
3. Which branch of anatomy examines structures too small to be seen with the naked eye?
A) Gross anatomy
B) Surface anatomy
C) Microscopic anatomy
D) Systemic anatomy
Correct Answer: Microscopic anatomy
Rationale: Microscopic anatomy, also called histology, examines structures that require a
microscope for visualization, such as cells and tissues. Gross anatomy studies large, visible
structures. Surface anatomy studies exterior features, and systemic anatomy studies organ
systems.
4. Which organ system is primarily responsible for exchanging gases with the
environment?
A) Cardiovascular system
B) Respiratory system
C) Urinary system
D) Digestive system
Correct Answer: Respiratory system
Rationale: The respiratory system, consisting of the lungs and airways, is responsible for
oxygen intake and carbon dioxide removal. The cardiovascular system transports gases,
the urinary system filters wastes, and the digestive system processes nutrients.
, 5. Which organ system regulates body functions through hormones?
A) Nervous system
B) Lymphatic system
C) Endocrine system
D) Integumentary system
Correct Answer: Endocrine system
Rationale: The endocrine system uses chemical messengers called hormones to regulate
body processes such as growth, metabolism, and reproduction. The nervous system uses
electrical impulses for rapid responses. The lymphatic system defends against pathogens,
and the integumentary system protects the body.
6. What is the correct order of structural organization from simplest to most complex?
A) Atom, Molecule, Cell, Tissue, Organ, Organ System, Organism
B) Cell, Atom, Molecule, Tissue, Organ, Organ System, Organism
C) Molecule, Atom, Cell, Tissue, Organ, Organ System, Organism
D) Atom, Cell, Molecule, Tissue, Organ System, Organ, Organism
Correct Answer: Atom, Molecule, Cell, Tissue, Organ, Organ System, Organism
Rationale: The structural hierarchy begins with atoms forming molecules, which combine
to form cells. Cells organize into tissues, tissues into organs, organs into organ systems,
and organ systems form the complete organism. This order reflects increasing complexity
from the chemical to the organismal level.
7. What is the smallest living unit of the human body?
