# BIOL 251 Module 1 Exam Review: Introduction to Anatomy, Physiology, and Chemistry of Life
## Section 1: Introduction to Anatomy & Physiology
**1. What is the primary focus of microscopic anatomy in the study of the human body?**
A) Investigating the functions of organ systems
B) Analyzing structures using a microscope
C) Examining the effects of diseases on organ systems
D) Studying the exterior features of the body
**Answer: B**
*Rationale:* Microscopic anatomy (histology) examines structures too small to be seen with the
naked eye, requiring a microscope for visualization. Gross anatomy focuses on large visible structures.
**2. Which of the following sequences correctly orders the levels of organization from simplest to
most complex in the human body?**
A) Organelle → Cell → Tissue → Organ → Organ System → Organism
B) Cell → Organelle → Tissue → Organ → Organ System → Organism
C) Organelle → Tissue → Cell → Organ → Organ System → Organism
D) Cell → Tissue → Organelle → Organ → Organ System → Organism
**Answer: A**
*Rationale:* The structural hierarchy begins with organelles (subcellular components), then cells,
tissues, organs, organ systems, and finally the whole organism. This sequence reflects increasing
complexity.
**3. What type of cells build the tissues of the human body according to cell theory?**
A) Viral cells
B) Prokaryotic cells
C) Eukaryotic cells
D) Bacterial cells
**Answer: C**
,*Rationale:* All human body cells are eukaryotic, characterized by having a true nucleus and
membrane-bound organelles. Prokaryotic cells (bacteria) are single-celled organisms without a
nucleus.
**4. The principle of complementarity in anatomy and physiology states which of the following?**
A) All organs function independently without affecting each other
B) A structure's shape (anatomy) determines its function (physiology)
C) Physiology is more important than anatomy
D) Anatomy and physiology are unrelated fields of study
**Answer: B**
*Rationale:* The principle of complementarity states that a structure's shape (anatomy) determines
its function (physiology). This is why we study both fields together.
**5. The study of how disease or injury impacts organs and organ systems is called:**
A) Gross anatomy
B) Microscopic anatomy
C) Pathological physiology
D) Systemic physiology
**Answer: C**
*Rationale:* Pathological physiology studies the impact of disease or injury to organs and organ
systems. This is also called pathophysiology.
**6. Which of the following is NOT a basic characteristic of life displayed by living organisms?**
A) Responsiveness
B) Reproduction
C) Inertia
D) Metabolism
**Answer: C**
*Rationale:* Inertia (resistance to change) is a physical property, not a characteristic of life. Living
organisms exhibit responsiveness, reproduction, metabolism, growth, and adaptation.
**7. The integumentary system includes which of the following structures in the human body?**
, A) Bones and joints
B) Skin, hair, and nails
C) Brain and spinal cord
D) Heart and blood vessels
**Answer: B**
*Rationale:* The integumentary system includes the skin, hair, nails, and associated glands. Bones
and joints are part of the skeletal system; brain and spinal cord are the nervous system; heart and
blood vessels are the cardiovascular system.
**8. The thoracic cavity is protected by the rib cage and contains which of the following organs?**
A) Brain and spinal cord
B) Heart and lungs
C) Stomach and intestines
D) Kidneys and bladder
**Answer: B**
*Rationale:* The thoracic cavity is the superior portion of the ventral cavity, enclosed by the ribs, and
houses the lungs and the heart (within the pericardial sac).
**9. A patient's body temperature rises to 102°F and the body responds by sweating and vasodilation
to cool down. This regulatory mechanism best illustrates which concept?**
A) Positive feedback
B) Negative feedback
C) Homeostatic imbalance
D) Set point elevation
**Answer: B**
*Rationale:* Negative feedback reverses a change from the set point. The rise in temperature triggers
responses that lower temperature, returning it toward normal. Positive feedback amplifies change.
**10. The study of the structure of body parts and their relationships to one another is known as:**
A) Physiology
B) Anatomy
