Exam Structure
The HESI A2 Anatomy & Physiology Examination is a critical component of nursing program admissions consisting of:
• 25–30 multiple-choice questions on the actual exam, with this comprehensive test bank containing 150 practice questions for thorough
preparation
• Section-specific time limits
• Percentage-based scoring with 75–80% minimum required by most programs and 85%+ recommended for competitive applicants
• Applied physiological understanding and cause-and-effect reasoning rather than simple memorization
Introduction
This HESI A2 Anatomy and Physiology Nursing Entrance Exam Preparation document for the 2026/2027 academic cycle reflects the official
Elsevier HESI Admission Assessment Exam requirements for nursing program admissions. The A&P section is consistently reported by students
as the most challenging portion of the HESI A2 because it tests applied physiological understanding rather than memorization of definitions.
The examination evaluates comprehensive understanding of human anatomy and physiology including: histology and the four fundamental tissue
types (epithelial, connective, muscle, nerve); skeletal system structure and function; muscular system contraction physiology; nervous system
organization and neurotransmission; endocrine feedback loops and hormone regulation; cardiovascular blood flow and cardiac output; respiratory
gas exchange and acid-base balance; renal filtration and fluid balance; digestive system processes; integumentary protection and thermoregulation;
reproductive system basics; homeostasis mechanisms; and physiological regulation under stress conditions.
The test bank emphasizes functional relationships, compensatory mechanisms, and system interactions—mirroring the actual HESI A2 approach
of testing consequences rather than isolated facts. Each question includes the correct answer in bold green followed by a detailed rationale that
reinforces evidence-based anatomical and physiological principles essential for nursing foundation success.
Answer Format
All questions must be presented in bold text for clear distinction and readability.
All correct answers must be presented in bold and green, followed by clearly defined, scientifically focused rationales that reinforce anatomical
structure, physiological function, homeostatic regulation, and clinical relevance for nursing practice.
, Section 1: Histology & Tissue Types (Questions 1-15)
Question 1: Which of the four primary tissue types is responsible for covering body surfaces and lining body
cavities?
A) Connective tissue
B) Epithelial tissue
C) Muscle tissue
D) Nervous tissue
Correct Answer: B) Epithelial tissue
Rationale: Epithelial tissue covers body surfaces (skin), lines body cavities and hollow organs, and forms glands. It functions in protection,
absorption, filtration, excretion, and secretion. Connective tissue supports and binds, muscle tissue produces movement, and nervous tissue controls
body functions.
Question 2: Which type of epithelial tissue is found in areas subject to abrasion, such as the skin and
esophagus?
A) Simple squamous epithelium
B) Stratified squamous epithelium
C) Simple columnar epithelium
D) Pseudostratified epithelium
Correct Answer: B) Stratified squamous epithelium
Rationale: Stratified squamous epithelium consists of multiple cell layers, providing protection against abrasion. It's found in skin (keratinized) and
esophagus/vagina (non-keratinized). Simple epithelia are found in areas of absorption/filtration where protection is less critical.
Question 3: Which connective tissue type contains the most abundant fibers and provides the greatest
tensile strength?
A) Areolar connective tissue
B) Dense regular connective tissue
C) Adipose tissue
D) Reticular connective tissue
Correct Answer: B) Dense regular connective tissue
Rationale: Dense regular connective tissue contains densely packed collagen fibers arranged in parallel, providing great tensile strength in one
direction. It forms tendons and ligaments. Areolar is loose connective tissue, adipose stores fat, and reticular forms supportive stroma.
Question 4: Which cell type is responsible for producing cartilage matrix?
, A) Osteocytes
B) Chondrocytes
C) Fibroblasts
D) Adipocytes
Correct Answer: B) Chondrocytes
Rationale: Chondrocytes are cartilage cells that produce and maintain the cartilage matrix. Osteocytes are bone cells, fibroblasts produce connective
tissue fibers, and adipocytes are fat cells. Cartilage is avascular and heals slowly due to limited nutrient supply.
Question 5: Which type of muscle tissue is voluntary and striated?
A) Cardiac muscle
B) Smooth muscle
C) Skeletal muscle
D) Visceral muscle
Correct Answer: C) Skeletal muscle
Rationale: Skeletal muscle is voluntary (under conscious control) and striated (has visible banding pattern). Cardiac muscle is striated but
involuntary. Smooth muscle is involuntary and non-striated, found in hollow organs and blood vessels.
Question 6: The functional unit of nervous tissue is the:
A) Neuroglia
B) Neuron
C) Axon
D) Dendrite
Correct Answer: B) Neuron
Rationale: The neuron is the functional unit of nervous tissue, responsible for receiving, processing, and transmitting information. Neuroglia are
supporting cells. Axons and dendrites are parts of neurons (axon transmits, dendrite receives signals).
Question 7: Which tissue type has the poorest blood supply and therefore heals most slowly?
A) Bone tissue
B) Cartilage
C) Skeletal muscle
D) Epithelial tissue
, Correct Answer: B) Cartilage
Rationale: Cartilage is avascular (no blood supply), receiving nutrients through diffusion from surrounding tissues. This makes it heal very slowly
compared to vascular tissues like bone, muscle, and epithelium which have rich blood supplies.
Question 8: Simple columnar epithelium is primarily found in the:
A) Skin surface
B) Digestive tract lining
C) Blood vessels
D) Urinary bladder
Correct Answer: B) Digestive tract lining
Rationale: Simple columnar epithelium lines the digestive tract from stomach to rectum. It's specialized for absorption and secretion, often containing
goblet cells that produce mucus. Skin has stratified squamous, blood vessels have simple squamous, and bladder has transitional epithelium.
Question 9: Which blood cell type is responsible for oxygen transport?
A) Leukocytes
B) Thrombocytes
C) Erythrocytes
D) Plasma cells
Correct Answer: C) Erythrocytes
Rationale: Erythrocytes (red blood cells) contain hemoglobin and transport oxygen from lungs to tissues. Leukocytes are white blood cells (immunity),
thrombocytes are platelets (clotting), and plasma cells produce antibodies.
Question 10: Transitional epithelium is unique because it:
A) Contains cilia
B) Can stretch and change shape
C) Produces mucus
D) Is keratinized
Correct Answer: B) Can stretch and change shape
Rationale: Transitional epithelium can stretch and change from multiple cell layers to fewer layers when distended. It's found in the urinary bladder,
ureters, and urethra where stretching occurs during filling. This adaptability prevents tearing during organ expansion.
Question 11: Which type of connective tissue stores energy and provides insulation?
