INTRODUCTION
Welcome to the BIO201 Anatomy & Physiology I final exam study guide. This comprehensive
resource is designed for StraighterLine students preparing for the cumulative final proctored
examination in Anatomy & Physiology I for the 2026/2027 academic year.
Course Overview:
• Course Code: BIO201
• Title: Anatomy & Physiology I
• Credits: 3
• Institution: StraighterLine
• ACE ID: OOSL-0028
• Academic Year: 2026/2027
Course Description:
This course provides a comprehensive look at the human body's structure and functions. Topics
include organization of the body, characteristics of life, anatomical terminology, how the body
maintains homeostasis, the relationship of chemistry to anatomy and physiology, cell function
and division, skin, skeletal system, muscles, nervous system, sensory organs, and the
endocrine system.
Four Core Domains:
1. Foundations of Anatomy & Physiology – Levels of organization, anatomical
terminology, homeostasis, chemistry for A&P, and the cell
2. Histology & Integumentary System – Tissues (epithelial, connective, muscle, nervous)
and the skin
3. Skeletal & Muscular Systems – Bones, joints, skeletal muscle histology, and
physiology of muscle contraction
4. Nervous & Endocrine Systems – Nervous tissue, spinal cord, brain, cranial nerves,
and endocrine glands
, DOMAIN 1: FOUNDATIONS OF ANATOMY & PHYSIOLOGY
Question 1
The basic unit of structure and function in the human body is the:
A. Tissue
B. Cell
C. Organ
D. System
cOrrect Answer: B ✓
rAtIOnAle: The cell is the basic unit of structure and function in the human body. All living
organisms are composed of cells, which are the smallest units capable of performing all life
processes.
Question 2
Which of the following levels of organization is correct from simplest to most complex?
A. Cell → Tissue → Organ → Organ system → Organism
B. Tissue → Cell → Organ → Organ system → Organism
C. Cell → Organ → Tissue → Organ system → Organism
D. Organ → Tissue → Cell → Organ system → Organism
cOrrect Answer: A ✓
rAtIOnAle: The correct hierarchy from simplest to most complex is: Cell → Tissue → Organ →
Organ system → Organism. Cells form tissues, tissues form organs, organs form organ
systems, and organ systems work together to form an organism.
Question 3
The study of the structure of body parts and their relationships is called:
A. Physiology
B. Histology
C. Anatomy
D. Cytology
cOrrect Answer: C ✓
rAtIOnAle: Anatomy is the study of the structure of body parts and their relationships.
Physiology is the study of how body parts function. Histology is the study of tissues, and
cytology is the study of cells.
