APHY 101 - Exam 1 lecture/lab Questions and
Correct Detailed Answers with Complete
Solutions | Graded A+ | New Update 2025-2026
anatomy - ANSWERS Study of body structures
physiology - ANSWERS Function of body structures and how they carry our life
sustaining activities
homeostasis - ANSWERS Ability to maintain relatively stable internal
environment regardless of external environment; balanced state of equilibrium
where changes are in a narrow range
Atom-molecule-macromolecule-organelle-cell-tissue-organ-organ system-
organism - ANSWERS Structural hierarchy of organization
Eight characteristics of living things - ANSWERS Boundary maintenance,
digestion, excretion, growth, reproduction, responsiveness, movement,
metabolism
Five factors necessary for survival - ANSWERS Oxygen, pressure, stable
temperature, nutrients, water
Three components of control mechanism - ANSWERS Affector (sensor),
Integrator (control center), effector (motor)
, Negative feedback loop - ANSWERS Most common, output system decreases
the input (org stimulus) into the system and loops to maintain homeostasis (ex:
maintain body temp)
Positive feedback loop - ANSWERS Rare, self-amplifying, the response
enhances the org. Stimuli and accelerates the activity (ex: blood clot, birth
process)
Anatomical position - ANSWERS face forward, arms at sides, palms anterior,
feet forward and parallel
axial - ANSWERS Head, neck, trunk
appendicular - ANSWERS Limbs and attach to axis points
cephalic - ANSWERS Pertaining to head
cranial - ANSWERS toward the head
nasal - ANSWERS Pertaining to nose
orbital - ANSWERS Pertaining to bony eye socket
buccal - ANSWERS Pertaining to cheek
