Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
The abdominal cavity contains the:
Correct Answer: C
Rationale: The abdominal cavity holds the spleen, below the diaphragm, unlike heart and lungs (B, thoracic), or trachea (D, thoracic/neck). Anatomically, it spans diaphragm to pelvis, housing digestive organs (e.g., spleen filters blood), making C correct.
Question 2 of 5
Which pairing of dissectional terms is most appropriate?
Correct Answer: D
Rationale: Superficial and deep pair as depth terms skin superficial, muscle deep unlike medial-proximal, superior-posterior, or proximal-lateral, which mix axes. Anatomically, these describe layering (e.g., dissection cuts), making D most cohesive.
Question 3 of 5
The study of the functions of cells, tissues, organs, and organ systems of the human body would best be described as:
Correct Answer: B
Rationale: Physiology studies how cells, tissues, organs, and systems function e.g., how muscles contract unlike homeostasis (A, a process), anatomy (C, structure), or pathology (D, disease). Anatomically, it complements structure (anatomy) by explaining processes like digestion or respiration. For instance, physiology details ATP production in mitochondria, not just their shape, making B the best description per standard biological definitions.
Question 4 of 5
Proteins are extremely important to the human body. Which of the following is not a function of protein?
Correct Answer: D
Rationale: Proteins protect (A, antibodies), catalyze (B, enzymes), repair (C, collagen), but don't primarily insulate organs fat does, per anatomical roles. Options CB-C5 list protein functions, but insulation (adipose tissue) is distinct. Proteins build structure (e.g., keratin) and regulate (enzymes), not thermal insulation, making D incorrect.
Question 5 of 5
When teaching respiratory anatomy to a client diagnosed with pneumonia who wants to know more about the respiratory tract, the nurse explains that the cells lining the respiratory tract are pseudostratified ciliated columnar epithelial cells that:
Correct Answer: D
Rationale: Pseudostratified ciliated columnar epithelial cells line the respiratory tract, with cilia moving mucus, per options 9-AB. They're single-layered (not A), protect via mucus (not abrasion, B), and aren't in vessels . Anatomically, cilia clear pathogens key in pneumonia making D correct.
