Bio 251- Anatomy & Physiology I - Chapter 1
Exam Prep Q&A
1. What is the primary focus of anatomy?: Anatomy investigates the body's structure, including
the size and shape of bones.
2. What does physiology study?: Physiology investigates the processes or functions of living things.
3. What is gross anatomy?: Gross anatomy examines structures without a microscope.
4. What is the difference between cytology and histology?: Cytology is the study of cells,
while histology is the study of tissues.
5. What imaging technique uses electromagnetic radiation?: X-ray imaging uses elec-
tromagnetic radiation to create radiographs.
6. How does ultrasound imaging work?: Ultrasound uses sound waves that bounce back to a
receiver to create a sonogram.
7. What is a CT scan?: A CT scan is a computer-analyzed series of x-ray images.
8. What is Digital Subtraction Angiography (DSA)?: DSA is similar to a CT scan but uses a
radiopaque dye to enhance image ditterences.
9. What does MRI stand for and how does it work?: MRI stands for Magnetic Resonance
Imaging, which uses radio waves in an electromagnetic field.
10. What does PET imaging detect?: PET detects radioactively labeled glucose usage by tissues to
provide metabolic information.
11. What is the goal of studying physiology?: The goal is to understand how the body responds
to stimuli and maintains stable internal conditions.
12. What is cell physiology?: Cell physiology examines processes occurring within cells.
13. What is systemic physiology?: Systemic physiology focuses on the functions of organ systems.
14. What are the four types of tissue?: The four tissue types are epithelial, connective, muscular, and
nervous.
15. What does the integumentary system do?: It provides protection, regulates temperature,
prevents water loss, and helps produce vitamin D.

, 16. What is the primary function of the skeletal system?: The skeletal system provides
protection, support, and allows body movements.
17. What is the role of the muscular system?: The muscular system produces body movements,
maintains posture, and generates heat.
18. What does the nervous system regulate?: The nervous system detects sensations and
controls movements and physiological processes.
