### Section 1: Anatomical Terminology & Body Organization (Questions 1-25)
**1. The study of the structure of body parts and their relationships to one another is
called:**
- A) Physiology
- B) Histology
- C) Anatomy
- D) Cytology
**Answer: C**
**Rationale:** Anatomy is the study of structure, while physiology is the study of
function. Histology is the study of tissues, and cytology is the study of cells.
---
**2. The study of the function of the body's structures is called:**
- A) Anatomy
- B) Physiology
- C) Pathology
- D) Embryology
,**Answer: B**
**Rationale:** Physiology focuses on how body parts work and carry out their life-
sustaining activities.
---
**3. Which level of organization is the simplest?**
- A) Tissue level
- B) Cellular level
- C) Chemical level
- D) Organ level
**Answer: C**
**Rationale:** The chemical level includes atoms and molecules and is the simplest
level of structural organization.
---
**4. The correct order of structural organization from simplest to most complex is:**
- A) Chemical, cellular, tissue, organ, organ system, organism
- B) Cellular, chemical, tissue, organ, organ system, organism
- C) Chemical, tissue, cellular, organ, organ system, organism
- D) Organism, organ system, organ, tissue, cellular, chemical
**Answer: A**
,**Rationale:** The human body is organized into several levels: chemical, cellular,
tissue, organ, organ system, and organism.
---
**5. A group of cells that work together to perform a specific function is called a(n):**
- A) Organ
- B) Tissue
- C) Organ system
- D) Organism
**Answer: B**
**Rationale:** Tissues are groups of similar cells that have a common function.
---
**6. The heart is an example of which level of structural organization?**
- A) Cellular
- B) Tissue
- C) Organ
- D) Organ system
**Answer: C**
**Rationale:** An organ is a structure composed of at least two tissue types that
performs a specific function for the body.
, ---
**7. The function of the integumentary system is to:**
- A) Support the body and protect internal organs
- B) Protect the body, regulate temperature, and prevent water loss
- C) Transport oxygen and nutrients
- D) Control body functions via hormones
**Answer: B**
**Rationale:** The integumentary system (skin, hair, nails) protects the body, regulates
temperature, and prevents water loss.
---
**8. Which organ system is responsible for support, protection of internal organs, and
movement?**
- A) Muscular system
- B) Skeletal system
- C) Nervous system
- D) Cardiovascular system
**Answer: B**
**Rationale:** The skeletal system provides support, protects organs, and serves as a
framework for muscle attachment.
