A&P Lecture I Delgado - Test #1
Questions and All Correct Answers.
Anatomy - Answer study of structure (size, shape, color, weight, location, composition)
Physiology - Answer study of function (the contribution to the body)
Why are anatomy and physiology studied together? - Answer The structure of a part of the
body often reflects its function.
Homeostasis - Answer maintaining a stable internal environment within the body
Two sub disciplines of anatomy - Answer Cell biology and histology
Two sub disciplines of physiology - Answer exercise physiology and immunology
List the six levels of structural organization - Answer 1) Chemical Level (atoms & molecules)
ex. DNA (deoxyribonucleic acid)
2) Cellular Level
ex. muscle cells
3) Tissue Level
ex. connective tissue
4) Organ Level
ex. heart
5) System Level
ex. Digestive System
6) Organism Level
ex. human
List the 11 organ systems of the body - Answer 1. Integumentary
2. Reproductive
3. Urinary
4. Digestive
5. Endocrine
6. Lymphatic
, 7. Skeletal
8. Nervous
9. Muscular
10. Cardiovascular
11. Respiratory
Which two organ systems serve as control centers in negative feedback loops controlling
homeostasis? - Answer Cardiovascular System and Endocrine System
How is a person's homeostasis challenged throughout the day? - Answer by either
-external environment i.e. heat
-internal environment i.e. skip breakfast - glucose level drops
List three components of a feedback loop - Answer 1) receptor - monitors changes
2) control center - evaluates information received & generates commands
3) effector - produces a response
Negative feedback loops - Answer reverses a change in a controlled condition or negates
original stimulus
ex. Rise in blood pressure, heart rate increases
or room temp gets to hot, A/C kicks on
Positive feedback loop - Answer enhance a change in one of the body's controlled conditions
ex. labor contractions during birth of baby
or microphone detecting voice
Disorder - Answer any abnormality of structure or function
Disease - Answer illness characterized by a recognizable set of signs and symptoms
Symptom - Answer subjective changes in body functions that are not apparent to an
observer
ex. headache, nausea, dizziness
