, Chapter 1 Introduction to the
Body
1. Which of the following represents the correct order of levels of organization in the
human body?
A. Tissue, organ, organism, system
B. Cell, tissue, organ, system, organism
C. Organ, system, tissue, cell
D. System, cell, organization, tissue
Correct Answer: B
Rationale: The levels of organization in the human body progress from cells to
tissues to organs to organ systems, culminating in the complete organism.
2. What is the primary function of epithelial tissue?
A. Support and structure
B. Communication
C. Protection and secretion
D. Movement
Correct Answer: C
Rationale: Epithelial tissue serves primarily to protect underlying structures, secrete
substances, and facilitate absorption.
3. Which body system is responsible for the regulation of hormones?
A. Nervous system
B. Endocrine system
C. Circulatory system
D. Immune system
Correct Answer: B
Rationale: The endocrine system is mainly responsible for hormone production and
regulation throughout the body for various functions including metabolism, growth,
and mood.
4. The study of the structure and function of the body is known as:
A. Anatomy
B. Physiology
C. Pathology
D. Histology
Correct Answer: A
Rationale: Anatomy is the branch of biology concerned with the study of the
structure of organisms, including their systems and organs.
,5. Which of the following is a role of connective tissue?
A. Covering body surfaces
B. Conducting electrical impulses
C. Providing support and binding other tissues
D. Facilitating movement
Correct Answer: C
Rationale: Connective tissue primarily functions to support, bind, and connect other
tissues, providing structural integrity to various organs.
6. Select all the options that describe functions of the integumentary system.
A. Protection against environmental hazards
B. Thermoregulation
C. Nutrient absorption
D. Sensory perception
Correct Answer: A, B, D
Rationale: The integumentary system, which includes the skin, performs protective
functions, regulates temperature, and offers sensation, but does not directly absorb
nutrients.
7. In which phase of homeostasis does the body restore an imbalance?
A. Stimulus
B. Control center
C. Response
D. Effector
Correct Answer: C
Rationale: Homeostasis involves correcting imbalances through responses from
effectors that restore the body to its ideal state.
8. Which term refers to the body’s ability to maintain stable internal conditions despite
changes in external environments?
A. Homeostasis
B. Metabolism
C. Anabolism
D. Catabolism
Correct Answer: A
Rationale: Homeostasis is the process through which the body regulates its internal
environment to maintain stable conditions required for survival.
9. Which of the following components are part of the axial skeleton?
A. Skull and vertebral column
B. Humerus and femur
C. Pelvic girdle
D. Rib cage and pelvis
Correct Answer: A
, Rationale: The axial skeleton includes the skull, vertebral column, and rib cage,
while the appendicular skeleton includes the limbs and girdles.
10. The anatomical position is characterized by which of the following?
A. Standing with arms at the sides and palms facing forward
B. Laying supine with feet together
C. Sitting with legs crossed
D. Standing with arms raised above the head
Correct Answer: A
Rationale: The anatomical position serves as a reference point in anatomy. It
describes the body standing upright with feet together, arms at the sides, and palms
facing forward.
11. A group of cells that work together to perform a specific function is called a:
A. Tissue
B. System
C. Organ
D. Cell
Correct Answer: A
Rationale: Tissues are groups of similar cells that work together to perform a specific
function, such as epithelial tissue or muscle tissue.
12. Which plane divides the body into right and left sections?
A. Frontal plane
B. Sagittal plane
C. Transverse plane
D. Oblique plane
Correct Answer: B
Rationale: The sagittal plane divides the body into right and left parts, while the
frontal and transverse planes divide it into anterior/posterior and superior/inferior
sections, respectively.
13. Which of the following represents an example of negative feedback in a physiological
process?
A. Blood clotting
B. Labor contractions during childbirth
C. Temperature regulation
D. Lactation in mothers
Correct Answer: C
Rationale: Negative feedback regulates body functions by reversing changes from a
set point, such as maintaining body temperature.
14. Which of the following body systems is responsible for transporting nutrients
throughout the body?
A. Respiratory system
