Question 1
Which level of structural organization is the smallest that can perform all
life functions?
A. Chemical
B. Cellular
C. Tissue
D. Organ
Correct ,,answer,,,: B
Rationale: The cell (B) is the smallest living unit. Chemical level (A) is
nonliving. Tissues (C) are groups of cells. Organs (D) are multiple
tissues.
Question 2
,Which body cavity contains the heart and lungs?
A. Abdominal cavity
B. Pelvic cavity
C. Thoracic cavity
D. Cranial cavity
Correct ,,answer,,,: C
Rationale: Thoracic cavity (C) contains heart (pericardial cavity) and
lungs (pleural cavities). Abdominal (A) contains digestive organs. Pelvic
(B) contains bladder/reproductive organs. Cranial (D) contains brain.
Question 3
Which plane divides the body into equal left and right halves?
A. Sagittal plane
B. Midsagittal (median) plane
C. Frontal (coronal) plane
D. Transverse plane
Correct ,,answer,,,: B
Rationale: Midsagittal (B) divides into equal left and right halves.
Sagittal (A) divides into unequal left/right. Frontal (C) divides
anterior/posterior. Transverse (D) divides superior/inferior.
Question 4
,Which directional term means “toward the midline”?
A. Lateral
B. Medial
C. Proximal
D. Distal
Correct ,,answer,,,: B
Rationale: Medial (B) means toward midline. Lateral (A) means away
from midline. Proximal (C) means closer to trunk. Distal (D) means
farther from trunk.
Question 5
Which organ system is responsible for filtering blood and producing
urine?
A. Digestive
B. Respiratory
C. Urinary
D. Endocrine
Correct ,,answer,,,: C
Rationale: Urinary system (C) includes kidneys, ureters, bladder,
urethra. Digestive (A) breaks down food. Respiratory (B) exchanges
gases. Endocrine (D) secretes hormones.
Question 6
, Which statement best describes homeostasis?
A. Complete stability of all body conditions
B. Maintenance of a relatively stable internal environment
C. Constant fluctuation without regulation
D. Response only to external stimuli
Correct ,,answer,,,: B
Rationale: Homeostasis (B) maintains dynamic equilibrium. A is
incorrect (not completely stable). C is opposite. D ignores internal
stimuli.
Question 7
Which type of feedback mechanism amplifies a change?
A. Positive feedback
B. Negative feedback
C. Neutral feedback
D. Inhibitory feedback
Correct ,,answer,,,: A
Rationale: Positive feedback (A) amplifies change (e.g., childbirth,
blood clotting). Negative feedback (B) reverses change. C and D are not
standard.
