(Questions)
Levels of Organization & Body Systems
1. Which of the following correctly lists the levels of structural
organization from smallest to largest?
A) Cellular, chemical, tissue, organ, organ system, organism
B) Chemical, cellular, tissue, organ, organ system, organism
C) Tissue, cellular, chemical, organ, organism, organ system
D) Chemical, tissue, cellular, organ system, organ, organism
Correct Answer: B
Rationale: The six levels of structural organization, from
,smallest to largest, are: chemical (atoms and molecules),
cellular, tissue, organ, organ system, and organism. This
hierarchy reflects increasing complexity in the human body.
2. The study of the structure of body parts and their
relationships to one another is called:
A) Physiology
B) Histology
C) Anatomy
D) Cytology
Correct Answer: C
Rationale: Anatomy is the study of structure, while physiology
is the study of function. Cytology is the study of cells, and
histology is the study of tissues.
3. The study of the function of body parts is called:
A) Anatomy
B) Physiology
C) Histology
D) Embryology
Correct Answer: B
Rationale: Physiology is the science of function—how body
parts work and carry out their life-sustaining activities.
4. The study of cells is called:
A) Histology
B) Cytology
,C) Gross anatomy
D) Physiology
Correct Answer: B
Rationale: Cytology is the scientific study of cells, a subdivision
of microscopic anatomy.
5. The study of tissues is called:
A) Cytology
B) Histology
C) Physiology
D) Embryology
Correct Answer: B
Rationale: Histology is the study of tissues—groups of similar
cells that work together to perform a specific function.
6. Which level of organization consists of groups of similar
cells that have a common function?
A) Chemical level
B) Cellular level
C) Tissue level
D) Organ level
Correct Answer: C
Rationale: The tissue level consists of groups of similar cells
that have a common function. The four primary tissue types are
epithelial, connective, muscle, and nervous tissue.
, 7. Which of the following is the smallest unit of matter?
A) Molecule
B) Cell
C) Atom
D) Organelle
Correct Answer: C
Rationale: An atom is the smallest unit of matter. Atoms
combine to form molecules, which then form organelles at the
chemical level of organization.
8. The chemical level of organization includes which of the
following?
A) Cells and organelles
B) Atoms, molecules, and organelles
C) Tissues and organs
D) Organ systems and organisms
Correct Answer: B
Rationale: The chemical level includes atoms, molecules, and
organelles—the building blocks of all structures in the body.
9. Which body system is primarily responsible for gas
exchange?
A) Cardiovascular system
B) Respiratory system
C) Digestive system
D) Nervous system
