ATI Prep
Q1. Which level of structural organization is the simplest?
A. Organ
B. Cellular
, C. Chemical ✅
D. Tissue
Explanation: The chemical level includes atoms and molecules, which are the simplest units.

All higher levels build upon this foundation.
Q2. Which system is primarily responsible for transporting nutrients and gases throughout
the body?
A. Respiratory
B. Digestive
C. Endocrine
D. Cardiovascular ✅
Explanation: The cardiovascular system includes the heart and blood vessels and is responsible
for circulating oxygen, nutrients, hormones, and waste products.
Q3. Homeostasis is maintained primarily through:
A. Positive feedback
B. Chemical buffers
C. Negative feedback ✅
D. Hormone secretion
Explanation: Most homeostatic control systems operate via negative feedback, which reduces or
eliminates the original stimulus.
, Q4. Which directional term means “farther from the point of attachment”?
Page | 3 A. Proximal
B. Medial
C. Distal ✅
D. Inferior
Explanation: “Distal” refers to parts of a limb further away from the body’s point of attachment
(e.g., the wrist is distal to the elbow).
Q5. The anatomical position is characterized by all of the following EXCEPT:
A. Body upright
B. Arms at sides
C. Palms facing backward ✅
D. Feet slightly apart
Explanation: In anatomical position, palms face forward, not backward. This standardized
position ensures consistent reference.
Q6. Which body cavity contains the brain?
A. Thoracic
B. Vertebral
C. Cranial ✅
, D. Abdominal
Explanation: The cranial cavity is a subdivision of the dorsal cavity and contains the brain.

Q7. Which organ system is responsible for protecting the body and regulating
temperature?
A. Muscular
B. Integumentary ✅
C. Lymphatic
D. Skeletal
Explanation: The integumentary system (skin, hair, nails) protects the body and helps regulate
temperature through sweat and blood flow.
Q8. The thoracic cavity is separated from the abdominopelvic cavity by the:
A. Pleura
B. Diaphragm ✅
C. Peritoneum
D. Mediastinum
Explanation: The diaphragm is a muscular sheet that divides the thoracic and abdominopelvic
cavities and aids in breathing.
