QUESTIONS & ☑VERIFIED ☑VERIFIED
ANSWERS WITH RATIONALES
FOUNDATIONS OF ANATOMY & PHYSIOLOGY
Q1: What is the difference between anatomy
and physiology?
☑VERIFIED ☑VERIFIED ANSWER: Anatomy is
the study of the structure of body parts,
whereas physiology is the study of
,the function of body parts .
Rationale: Physiological functions depend on
anatomical structures, making the two
disciplines difficult to separate .
Q2: What are the levels of organization of life
from simplest to most complex?
☑VERIFIED ☑VERIFIED ANSWER: Subatomic
particles → atom → molecule →
macromolecule → organelle → cell → tissue →
organ → organ system → organism .
Rationale: Each level builds upon the previous,
with cells being the basic unit of structure and
function in all organisms .
Q3: Define homeostasis.
☑VERIFIED ☑VERIFIED ANSWER: The body's
maintenance of a stable internal environment .
,Rationale: Homeostasis exists if concentrations
of water, nutrients, and oxygen are balanced
and heat and pressure remain within certain
limited ranges .
Q4: What is a homeostatic mechanism?
☑VERIFIED ☑VERIFIED ANSWER: Self-
regulating control systems that maintain
homeostasis, such as those regulating body
temperature and blood pressure .
Rationale: These mechanisms typically involve
negative feedback to reverse changes and
return the body to its set point.
Q5: Maintaining a stable internal environment
typically requires which type of mechanism?
☑VERIFIED ☑VERIFIED ANSWER: Negative
feedback mechanism .
, Rationale: Negative feedback reverses a change
to bring the body back to homeostasis, unlike
positive feedback which amplifies changes.
Q6: What is anatomical position?
☑VERIFIED ☑VERIFIED ANSWER: Body facing
forward, feet parallel, arms at sides with palms
facing forward .
Rationale: All directional terms (superior,
inferior, anterior, posterior, medial, lateral) are
based on this standardized reference position.
Q7: A body has been sectioned with one
whole lung per section and the urinary bladder
split in half. What type of section is this?
☑VERIFIED ☑VERIFIED ANSWER: Sagittal .
Rationale: A sagittal plane divides the body into
