BIO 251 HUMAN ANATOMY AND
PHYSIOLOGY I ACTUAL SCRIPT 2026
QUESTIONS WITH ANSWERS GRADED A+
●● What does physiology study?
Answer: Physiology investigates the processes or functions of living
things.
●● What is gross anatomy?
Answer: Gross anatomy examines structures without a microscope.
●● What is the difference between cytology and histology?
Answer: Cytology is the study of cells, while histology is the study of
tissues.
●● What imaging technique uses electromagnetic radiation?
Answer: X-ray imaging uses electromagnetic radiation to create
radiographs.
●● How does ultrasound imaging work?
Answer: Ultrasound uses sound waves that bounce back to a receiver to
create a sonogram.
,●● What is a CT scan?
Answer: A CT scan is a computer-analyzed series of x-ray images.
●● What is Digital Subtraction Angiography (DSA)?
Answer: DSA is similar to a CT scan but uses a radiopaque dye to
enhance image differences.
●● What does MRI stand for and how does it work?
Answer: MRI stands for Magnetic Resonance Imaging, which uses radio
waves in an electromagnetic field.
●● What does PET imaging detect?
Answer: PET detects radioactively labeled glucose usage by tissues to
provide metabolic information.
●● What is the goal of studying physiology?
Answer: The goal is to understand how the body responds to stimuli and
maintains stable internal conditions.
●● What is cell physiology?
Answer: Cell physiology examines processes occurring within cells.
●● What is systemic physiology?
, Answer: Systemic physiology focuses on the functions of organ systems.
●● What are the four types of tissue?
Answer: The four tissue types are epithelial, connective, muscular, and
nervous.
●● What does the integumentary system do?
Answer: It provides protection, regulates temperature, prevents water
loss, and helps produce vitamin D.
●● What is the primary function of the skeletal system?
Answer: The skeletal system provides protection, support, and allows
body movements.
●● What is the role of the muscular system?
Answer: The muscular system produces body movements, maintains
posture, and generates heat.
●● What does the nervous system regulate?
Answer: The nervous system detects sensations and controls movements
and physiological processes.
●● What is the function of the endocrine system?
