Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 4
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 2 of 4
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 3 of 4
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.
Question 4 of 4
A nursing student is confused when the term matrix of the blood is used. What alternate term can the nurse use to help the student understand?
Correct Answer: D
Rationale: Blood's matrix is plasma , the fluid portion, per options CD-C7. Cells (WBCs A, platelets B, RBCs C) are suspended in it. Anatomically, plasma (55% of blood) carries nutrients e.g., in anemia making plasma' a clearer term, confirming D.
