Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
The thoracic and abdominopelvic cavities are separated by the:
Correct Answer: A
Rationale: The diaphragm, a muscular sheet, separates thoracic (chest) and abdominopelvic cavities, unlike mediastinum (B, chest divider), sternum (C, breastbone), or ventral cavity (D, broader). Anatomically, it regulates breathing and cavity distinction, confirming A.
Question 2 of 5
Emily needs to have her gall bladder removed. Her incision would be in the ___ quadrant of the abdominopelvic cavity.
Correct Answer: C
Rationale: The gallbladder, under the liver, is in the upper right quadrant, not left (A, B) or lower right. Surgical anatomy uses quadrants for precision, guiding incisions like cholecystectomy, making C correct.
Question 3 of 5
The female reproductive system includes which body parts?
Correct Answer: B
Rationale: The female reproductive system includes ovaries, not testes (A, male), femur (C, bone), or thyroid (D, endocrine). Anatomically, ovaries produce eggs, central to female reproduction, confirming B.
Question 4 of 5
A disease that affects the entire body or involves several organ systems is referred to as:
Correct Answer: B
Rationale: Systemic diseases affect multiple systems (e.g., diabetes), not chronic (A, long-term), acute (C, short-term), or local (D, confined). Anatomical terminology clarifies disease scope, making B correct.
Question 5 of 5
The lungs are situated within which body cavity?
Correct Answer: B
Rationale: The lungs reside in the thoracic cavity, within the chest, enclosed by the ribcage and diaphragm. The cranial cavity houses the brain, abdominal the stomach, pelvic the bladder, and spinal the spinal cord. Anatomically, the thoracic cavity's pleural subdivisions protect and support lung function breathing making B the correct choice, aligning with respiratory anatomy.
