Chapter 1-4 Anatomy and Physiology
Predictor Revision Questions and
Answers (2026)
Anatomy - correct answer: the study of the structure of the body
Physiology - correct answer: the study of the function of the body
Chemical level - correct answer: represents the atoms and molecules that make up cells
(Consists of Atomic level and molecular level)
Cellular level - correct answer: represents the basic unit of all living things
Tissue level - correct answer: a group of cells with similar or common function
Organ level - correct answer: a group of tissues with similar or common function
Organ system level - correct answer: a group of organs with similar or common function
Organismic level - correct answer: the entire body consisting of the various organ systems.
Integumentary System - correct answer: controls body temperature & protects body from
environmental hazards
Skeletal System - correct answer: supports body, protects soft body parts, stores minerals, forms
blood cells
,Muscular System - correct answer: movement, support and produces heat
Nervous System - correct answer: controls immediate responses to stimuli
Endocrine System - correct answer: controls long-term responses in body
Cardiovascular System - correct answer: internal transport of nutrients, wastes, oxygen, carbon
dioxide and cells
Lymphatic & Immune Systems - correct answer: defense, immunity and returns lost fluids to
cardiovascular system
Respiratory System - correct answer: exchange of air and delivery of blood gases to/from tissues
Digestive System - correct answer: ingestion, breakdown and absorption of food & elimination
of indigestible wastes
Urinary System - correct answer: filtration of blood to maintain proper water and salt balance
and to eliminate waste products
Reproductive System - correct answer: produces sex cells and hormones related to reproduction
homeostasis - correct answer: condition in which body's internal environment remains within
certain narrow physiological limits
homeostatic regulation - correct answer: adjustment of physiological system to maintain
homeostasis
,receptor - correct answer: monitors change in controlled condition (stimulus) and sends input to
control center
control (integration) center - correct answer: receives input from receptor & determines
appropriate response
effector - correct answer: cell or organ that receives information (output) from control center
and produces a response (effect)
interactions of a feedback system - correct answer: stimulus -> receptor -> input (afferent
pathway) -> control center -> output (efferent pathway) -> response
positive feedback - correct answer: the response by the effector to the initial change is to
further exaggerate the change. Example in labor contractions, the contraction of the uterus
forces the baby towards the birth canal, which
places pressure on the cervix; the pressure of the baby against the cervix causes uterine
contraction, etc. - correct answer: ...
Negative feedback - correct answer: the response by the effector to the initial change is to
counter or reduce that change, thus bringing the system back to its "normal" state. Example
When blood sugar level rises, the pancreas secretes
insulin which causes the cells of the body to take in glucose, thus removing glucose from the
blood and lowering blood sugar level. - correct answer: ...
Anatomical position - correct answer: patient is erect, feet apart and palms facing anteriorly
Cephalic = head
Cranial - correct answer: upper portion of head surrounding brain
, Facial - correct answer: face
cervical - correct answer: neck
thoracic - correct answer: chest
axillary - correct answer: armpit
acromial - correct answer: point of shoulder
deltoid - correct answer: fleshy portion of shoulder
brachial - correct answer: upper arm
antebrachial - correct answer: forearm
antecubital - correct answer: front of elbow
carpal - correct answer: wrist
manual - correct answer: hand
digital (phalangeal) - correct answer: fingers or toes
abdominal - correct answer: region of trunk between diaphragm and pelvis
