Section 1: Introduction to Anatomy & Physiology — Levels of Organization,
Homeostasis, and Terminology
Questions 1–20
1. Which of the following is the correct order of structural organization in the
human body, from simplest to most complex?
• A) Organ → Tissue → Cellular → Chemical → Organ System → Organism
• B) Chemical → Cellular → Tissue → Organ → Organ System → Organism
• C) Cellular → Chemical → Tissue → Organ → Organ System → Organism
• D) Chemical → Tissue → Cellular → Organ → Organ System → Organism
Answer: B
Rationale: The levels of structural organization are: chemical (atoms/molecules),
cellular, tissue, organ, organ system, and organism.
,2. The ability of the body to maintain relatively stable internal conditions
despite external changes is called:
• A) Metabolism
• B) Homeostasis
• C) Anabolism
• D) Catabolism
Answer: B
Rationale: Homeostasis is the maintenance of a relatively stable internal
environment.
3. Which of the following is an example of a normally occurring positive-
feedback mechanism in the human body?
• A) Regulation of blood glucose
• B) Stretching of the uterus near the end of pregnancy
• C) Regulation of body temperature
• D) Maintenance of blood pressure
Answer: B
Rationale: Positive feedback amplifies a response. Stretching of the uterus during
labor causes stronger contractions, which further stretches the uterus.
4. In the anatomical position, the subject is:
, • A) Lying face down
• B) Standing upright, facing forward, with arms at sides and palms facing
forward
• C) Lying on the back with palms facing down
• D) Standing with arms crossed over the chest
Answer: B
Rationale: The anatomical position is standing erect, facing forward, arms at the
sides, with palms and feet facing forward.
5. The term "proximal" means:
• A) Away from the midline
• B) Closer to the point of attachment to the trunk
• C) Farther from the point of attachment to the trunk
• D) Toward the back
Answer: B
Rationale: Proximal means nearer to the point of attachment or origin (e.g., the
elbow is proximal to the wrist).
6. Which body cavity contains the brain?
• A) Thoracic cavity
• B) Abdominal cavity
• C) Cranial cavity
• D) Pelvic cavity
, Answer: C
Rationale: The cranial cavity houses the brain.
7. The stomach is located in which body cavity?
• A) Thoracic cavity
• B) Abdominal cavity
• C) Cranial cavity
• D) Pelvic cavity
Answer: B
Rationale: The abdominal cavity contains the stomach, liver, intestines, and other
digestive organs.
8. Which of the following is an example of a negative feedback mechanism?
• A) Blood clotting
• B) Regulation of blood glucose levels
• C) Uterine contractions during childbirth
• D) Lactation
Answer: B
Rationale: Negative feedback reverses a change to maintain homeostasis. Blood
glucose regulation is a classic example (insulin lowers high glucose, glucagon
raises low glucose).
