EXAM STUDY GUIDE QUESTIONS
AND VERIFIED CORRECT DETAILED
ANSWERS 100% PASS
Define anatomy. Define physiology. Understand how the two terms are different
but "go together."
Anatomy- The study of the body structure.
Physiology- The study of body function.
The structure of organs determines their function.
List the levels of organization from lowest level to highest level.
Define each of the levels.
Chemical
cellular,
tissue
organ
organ system
organism.
Cell
The basic unit of structure and function in all organisms.
All living things consist of cells.
List the environmental factors which are requirements of organisms
, Water
Food
Oxygen
Heat
pressure
Define homeostasis
The maintenance of a stable internal environment.
Why is homeostasis important?
It keeps internal conditions stable for survival and function.
What systems control homeostasis? How do they control it?
The nervous and endocrine systems detect changes and respond with
impulses or hormones.
Name the 3 parts of a homeostatic mechanism
Receptor (detects change)
control center (processes info)
effector (carries out response).
Explain what a negative feedback mechanism is and why it is important.
, It reverses a change to keep a variable within normal limits. It maintains
stability. (ex. body temperature).
Explain what a positive feedback mechanism is and why they aren't common in the
human body.
It amplifies a change and is usually short-term. Rare because it can push
body out of balance. (ex. childbirth)
Be able to give examples of negative and positive feedback mechanisms in the
body.
Negative: body temp regulation, blood sugar levels.
Positive: childbirth, blood clotting.
Define the axial and appendicular portions of the body
Axial: Head, neck, trunk
Appendicular: Limbs (arms and legs)
List the major cavities of the body and explain what is contained within those
cavities.
Cranial (brain)
Vertebral (spinal cord)
Thoracic (heart, lungs)
Abdominopelvic (digestive organs, bladder)
