Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
Which term best defines the position of the knee relative to the hip?
Correct Answer: C
Rationale: The knee is distal to the hip, farther from the trunk's attachment, not lateral, medial, posterior, or proximal (E, closer). Anatomically, distal orients limbs knee below hip joint key for movement analysis, confirming C.
Question 2 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 3 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 4 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.
Question 5 of 5
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.
