I. Introduction to Anatomy & Physiology / Basic Chemistry
(Q1–25)
1. Which level of organization is the most complex?
A. Cellular level
B. Tissue level
C. Organ level
D. Organ system level
Answer: D
Rationale: The levels of organization from simplest to most
complex are: chemical → cellular → tissue → organ → organ
system → organism. Organ systems work together to form the
complete organism.
2. Which plane divides the body into anterior and posterior
portions?
A. Sagittal plane
,B. Midsagittal plane
C. Frontal (coronal) plane
D. Transverse plane
Answer: C
Rationale: The frontal (coronal) plane divides the body into
anterior (front) and posterior (back) portions. The sagittal plane
divides into left and right. The transverse plane divides into
superior and inferior.
3. The stomach is located in which body cavity?
A. Thoracic cavity
B. Abdominal cavity
C. Pelvic cavity
D. Cranial cavity
Answer: B
Rationale: The stomach is located in the abdominal cavity,
which is part of the ventral body cavity. The thoracic cavity
contains the heart and lungs. The pelvic cavity contains
reproductive organs and bladder.
4. Which term describes a position closer to the point of
attachment?
A. Distal
B. Proximal
C. Lateral
D. Medial
Answer: B
Rationale: Proximal means closer to the point of attachment or
, origin. Distal means farther from the point of attachment. For
example, the elbow is proximal to the wrist.
5. Homeostasis is best defined as:
A. The ability to grow and reproduce
B. The maintenance of a stable internal environment
C. The process of cell division
D. The breakdown of nutrients for energy
Answer: B
Rationale: Homeostasis is the body's ability to maintain a
relatively stable internal environment despite external changes.
It involves negative and positive feedback mechanisms.
6. In a negative feedback mechanism, the response:
A. Amplifies the original stimulus
B. Reverses the original stimulus
C. Has no effect on the stimulus
D. Creates a new stimulus
Answer: B
Rationale: Negative feedback mechanisms reverse or negate the
original stimulus to maintain homeostasis. For example, when
body temperature rises, mechanisms activate to cool the body.
Positive feedback amplifies the stimulus.
7. Which is an example of a positive feedback mechanism?
A. Body temperature regulation
B. Blood glucose regulation
C. Blood clotting
D. Blood pressure regulation
